Danger Keep Out Retractable Barrier for Outdoor Use
A striped belt identifies a hazard, while a belt printed Danger Keep Out gives a direct instruction not to enter. That distinction is central to the BQT450D. It carries two belts, both printed Danger Keep Out in white on red. The upper belt sits at the height normally expected for a barrier, while the second runs below it to repeat the message and close the lower gap left by a single-belt setup. Both belts retract slowly through braked cassettes for a more controlled return. The post is made from red powder-coated steel. Concrete inside the base helps keep the post stable when the neighbouring belt is pulled tight, while a rubber ring underneath adds grip on gravel and helps protect finished floors. Particularly well suited to plant rooms, loading bays and live work areas where access needs to be prevented rather than simply discouraged.
Why Use a Twin Belt Safety Barrier on Site
- Danger Keep Out on both belts: The same message appears on both belts, so it remains visible whichever one is noticed first. White wording on red provides a clear stop message, with the print remaining readable in dull light and beneath floodlights on a winter afternoon.
- Words leave no room to argue: A striped belt may be interpreted as marking a route or identifying a hazard, while Danger Keep Out gives a specific instruction. Where people need to remain outside an area rather than simply take care around it, printed wording makes the purpose of the barrier clearer.
- A warning at two heights: The upper belt sits at adult eye level and the lower one at a child's. This is useful anywhere members of the public pass the barrier, while also keeping the warning visible to people who are kneeling, seated or working lower down near the line.
- Belts that wind back slowly: The constant torque spring maintains even tension whether the belt is extended a short distance or to its full reach, helping prevent sagging. A brake controls the return so the belt retracts steadily rather than snapping back quickly.
- Holds still when the belt is pulled: A tensioned belt pulls the two posts towards each other. The concrete packed inside each base keeps most of the weight low down, while the rubber ring underneath adds grip to help reduce movement across the floor.
- Clips onto barriers you already own: The belt end connects with other makes of retractable barrier as well as this one. Printed posts can therefore be added to an existing set where specific wording is required, while plain barriers continue along the rest of the run.
Which Sites Need an Outdoor Barrier Post
| Loading Bays and Delivery Yards | Reversing lorries, lowering tail lifts and moving pallets can all require people to stay clear. A printed belt makes it clear that the area is closed rather than simply busy, giving visiting drivers a visible instruction without relying on someone being there to explain it. |
| Plant Rooms and Machinery Areas | Use the barrier around boiler rooms, lift motor rooms or machinery left open while an engineer is working. The wording gives a clear instruction to anyone entering the area, including staff who regularly pass the usual site markings. |
| Emergency Access and Fire Routes | Keep fire exits, hydrants and appliance bays clear of parking or stored items. A printed belt provides a more explicit instruction than a painted line and can be repositioned as the use of the building changes during the week. |
| Roadworks and Street Repairs | Mark pavement openings, exposed utility chambers and equipment positioned near the kerb. The printed wording helps direct people around the closure without requiring someone to remain beside it, and can be read by people approaching from either direction. |
| Schools, Hospitals and Public Buildings | Useful for repairs taking place while the building remains open and contractors share corridors with the public. The lower belt is particularly relevant here because it places the warning closer to a child's eye line while also closing the lower gap. |
| Live Worksites in Occupied Premises | Use the barrier around shop fitting works behind a temporary line, flooring being replaced overnight or ceilings opened between trading hours. The closure can be positioned when work begins and removed again before the area reopens. |
Wording or Chevrons, One Belt or Two?
Where one printed line is sufficient, the single belt Danger Keep Out barrier uses the same format with one cassette. For areas that need marking rather than fully closing, the twin belt red and white chevron barrier replaces the wording with a hazard pattern. A third belt option is printed Caution Do Not Enter.

The Displaysense BQT450D is a twin belt printed safety barrier, searched as a danger keep out barrier, a warning belt stanchion or a keep out barrier post. Danger Keep Out is printed in white on red along both belts, the upper one at adult reading height and the lower one down at a child’s eye line. Printed wording issues an instruction where a plain or patterned belt only signals that something is wrong, which is the difference between an area being marked and an area being shut. Each belt draws out to 3.4m. A constant torque spring inside every cassette keeps tension even at any extension, and a brake governs the return so the belt cannot snap. Universal locks on the belt ends will join rival systems as well as this one. The post measures 1015mm in powder-coated steel, standing on a 355mm galvanised base packed with concrete, which resists a tight belt pulling a post towards its neighbour, and rubber across the underside grips outside and protects floors indoors. 9kg total weight. Works inside and out. Specified by loading bays, delivery yards, plant rooms, machinery areas, emergency access routes, roadworks, schools, hospitals, public buildings and live worksites inside occupied premises. Companion versions carry one belt, red and white chevrons, or Caution Do Not Enter. Displaysense, UK display product specialists since 1978.
Printed wording changes how people respond to a barrier, which is the main reason to choose it over a plain belt. Stripes may be noticed without being interpreted as a direct instruction, while words tell people exactly what is expected. In shared corridors used by staff, contractors and the public, a striped belt can be mistaken for something that is simply marking out an area. Danger Keep Out makes the purpose of the closure much clearer and gives supervisors a visible instruction to refer to if access is challenged.
A child's eye line sits much lower than an adult's, which many standard barriers do not account for. Repeating the same wording on a second belt below the first places the message closer to where a child is looking, which is useful in hospital corridors, schools during term time and shopping centres where work is taking place behind a barrier. The lower belt also serves a second purpose by closing the knee height gap left beneath a single belt.
Inside each cassette, a constant torque spring keeps the belt under even tension whether it is extended a metre or pulled to its full reach. A conventional spring can tighten as it extends, leaving short spans very taut while longer ones are more prone to sagging where the wording needs to remain readable. A brake controls the return as well, so the belt comes back steadily rather than snapping in quickly when released.
Uneven ground can quickly expose the limitations of a poorly supported barrier base. Gravel, worn tarmac and yard concrete are rarely completely flat, so a base resting on only a few contact points may rock. A full rubber ring instead makes contact around the underside, helping the post stay steadier on irregular surfaces. The ring also works with the weight inside the base to resist the sideways pull created when a belt is drawn taut between two posts. Galvanising adds protection for outdoor use, allowing the base to remain on site and be cleaned down along with the rest of the equipment.

Marking Out a Whole Site?
Many sites combine printed and plain barriers, using wording where entry needs to be refused and plain belts along the rest of the run. Tell us what you are closing and we can suggest how to divide the layout, along with the number of posts required for each section.

The Displaysense BQT450D is a printed twin belt safety barrier, known to buyers as a keep out barrier post or a warning belt stanchion. Its belts read Danger Keep Out, which issues an instruction where a patterned belt only flags that a hazard exists. Both belts carry the print. The upper sits at adult reading height, the lower at roughly a child’s eye line, and that lower belt also blocks the knee height route people duck through. Belts draw out to 3.4m apiece. Every cassette runs a constant torque spring, holding tension steady whatever the span, and a brake on the return removes the snapback risk. Belt end locks are universal and will join rival systems. Post 1015mm, powder-coated steel. The 355mm base is galvanised, with concrete packed inside to resist the sideways pull of a taut belt. Rubber covers the entire underside, finding grip on gravel and guarding finished floors indoors. 9kg total weight. Works inside and out. Chosen by loading bays, plant rooms, emergency access routes, roadworks, schools, hospitals and live worksites in occupied buildings. Sibling versions come with one belt, with chevrons, or printed Caution Do Not Enter. Displaysense, UK display product specialists since 1978.
Full specification for this twin belt Danger Keep Out barrier, covering the post and base as one complete assembled unit. Measure the opening you need to close and allow for a post at every corner as well as at both ends of the run.
| Specification | Detail | What This Means for You |
|---|---|---|
| Belt Print | Danger Keep Out, white on red, both belts | The wording gives a direct instruction rather than simply identifying a hazard, making it suitable where access needs to be refused rather than merely discouraged. |
| Belts Fitted | Two, upper and lower | The upper belt sits at adult reading height while the lower one is positioned at a child's eye line, also closing the knee height gap left beneath a single belt. |
| Belt Length | 3.4m per belt | Posts can be spaced up to 3.4m apart, helping close wider openings with fewer barriers. Around corners, using a shorter span keeps the belt tighter and the line straighter. |
| Belt Cassette | Constant torque spring with brake | The constant torque spring keeps belt tension even at different extensions, while the brake controls the return so the belt does not snap back quickly when released. |
| Belt End | Universal lock | The universal lock connects with other makes of retractable barrier as well as its own, allowing printed posts to be added to an existing fleet where specific wording is needed. |
| Base | Galvanised, concrete cored, 355mm across | The concrete concentrates most of the weight in the base, helping resist the sideways pull created by a taut belt. The galvanised finish also suits prolonged outdoor use and can be hosed down during cleaning. |
| Base Underside | Full rubber protection ring | The full rubber ring makes contact across the underside on gravel and worn tarmac, helping reduce rocking while also keeping bare metal away from finished indoor floors. |
| Connection Points | Four on every post | One connection point pays out the post's own belt while the other three accept belts from neighbouring posts, allowing a closure to turn around obstacles, form a T junction or return on itself. |
| Post | 1015mm, red powder-coated steel | The height positions the upper belt where a boundary is normally expected, leaving space for the second belt below, while the red finish provides a visible warning before the wording can be read. |
| Total Weight | 9kg | At 9kg total weight, the barrier can be lifted and positioned by one operative, with most of that weight concentrated in the base rather than higher up the post. |
| Environment | Works inside and out | Suitable for both environments, the same barrier can be used in a plant room or an open yard without needing separate indoor and outdoor models. |
| Also Available | Single belt, chevron belts, Caution Do Not Enter | The same post is also available with one printed cassette, with red and white chevrons instead of wording, or carrying a different printed instruction. |

Questions About Printed Danger Keep Out Barriers
Q: What is the best safety barrier for closing off a work area?
A: The BQT450D is particularly well suited to closing off work areas, with Danger Keep Out printed along two 3.4m belts. The wording gives a direct instruction rather than simply identifying a hazard, making the purpose of the closure clearer, and the message is repeated across both belts.
Q: Is a printed belt barrier better than a chevron belt barrier?
A: They serve different purposes. Chevrons give a visible warning that a hazard is present, while printed wording addresses the reader directly and tells them what action to take. Use wording where access needs to be refused and choose chevrons where an area needs marking rather than closing.
Q: Do both belts on the Danger Keep Out barrier carry the wording?
A: Yes. Danger Keep Out appears in white on red along both the upper and lower belts, so the instruction is visible whichever one is noticed first. The upper belt sits at adult reading height, while the lower belt is positioned at roughly a child's eye line.
Q: Why does the lower belt on a twin belt barrier sit so low?
A: It serves two purposes. The lower position places the wording around a child's eye line, which is useful in schools, hospitals and public buildings where work may continue around visitors. It also closes the knee height gap left beneath a single belt, making the boundary harder to duck under.
Q: What is a constant torque spring in a retractable barrier?
A: A constant torque spring keeps the belt under even tension regardless of how far it is extended. A conventional spring can tighten as the belt is pulled out, leaving short spans very taut and longer spans more prone to sagging. Constant torque helps keep the line straight across different span lengths.
Q: Can a retractable belt barrier snap back and injure someone?
A: This barrier uses a controlled return that draws the belt back steadily rather than allowing it to whip in quickly. The benefit is particularly noticeable on sites where the same line is opened and reset several times during the day.
Q: Will an outdoor safety barrier stand up on gravel or broken tarmac?
A: Yes. The full rubber ring beneath the base makes contact around the complete circle rather than resting on a few separate points, helping reduce rocking on uneven ground. It also adds grip when the belts are pulled taut, helping prevent the posts from sliding towards each other.
Q: Can a Danger Keep Out barrier be used indoors as well as outside?
A: Yes, it is rated for both environments. The same barrier can be used in a plant room, hospital corridor or open delivery yard without needing separate indoor and outdoor models. Indoors, the rubber ring helps protect the floor instead of providing grip on rougher ground.
Q: Will these barrier posts connect to plain belt barriers we already own?
A: In many cases, yes. The belt ends use a universal lock designed to connect with other systems as well as this one. Printed posts can therefore be added where specific wording is required while plain barriers continue along the rest of the run. Testing one against your existing posts first is worthwhile, as some older systems use proprietary fittings.
Q: How many retractable barrier posts do I need to close an opening?
A: Divide the width being closed by the belt length, then allow one additional post so the line has support at both ends. Every corner also needs its own post. Send us the dimensions and we will check the quantity before you order.
Q: Is one printed belt enough, or should I fit a twin belt barrier?
A: A single printed belt can suit trained staff who respect a marked boundary. Twin belts provide a more substantial closure where the public has access, where children pass or where people have previously crossed the barrier. The single belt Danger Keep Out version uses one cassette and is otherwise identical.
Q: Is the Danger Keep Out barrier available with free UK delivery?
A: Yes. The BQT450D includes free UK mainland delivery and a 28-day returns policy. Displaysense has supplied UK sites with display and safety products since 1978. Where Danger Keep Out is stronger than the situation requires, the same belt is available with Caution Do Not Enter instead, while a chevron version suits areas that need marking rather than closing.
Keeping People Away From a Hazard
A closure is most effective when the barrier and the wording around it support each other and are both encountered before someone reaches the hazard. Signage on its own may not be enough, and neither is a barrier that is easy to overlook. These guides explain how different barrier types compare, how large crowds can be managed safely, how signage supports clear communication and what was involved in signing a 960 acre venue during a British Grand Prix weekend.
