The Displaysense SF3040B is a wall-mounted snap frame, 793mm wide by 1047mm high by 11mm deep, with anodised aluminium. It is delivered free to UK Mainland.
This is the large format frame in the Displaysense snap frame range. The SF3040B takes a 30 x 40 inch poster and mounts flat to a wall in either portrait or landscape. The aluminium profile is finished in black with mitred corners, so the four edges meet cleanly rather than butting up square. All four sides hinge open at the front, so a poster gets swapped while the frame stays screwed to the wall. An anti-glare cover sheet sits over the print and holds it flat against the backing board. Wall fixings are supplied, and the frame sits close to the wall rather than standing proud of it. Best suited for NHS receptions, school corridors and retail floors, where the content on the wall changes often, the wall itself is in public view, and whoever swaps the poster is fitting it around another job.
| NHS Receptions and Waiting Areas | Health campaigns change with the season and the guidance behind them changes faster. A frame that opens on the wall means a receptionist swaps a poster between patients rather than waiting for maintenance to come and take it down. |
| School and College Corridors | Safeguarding notices, exam timetables and open evening artwork all live on corridor walls. Large format reads at walking pace, and a fixed frame holds the print flat right through to half term without a corner lifting anywhere. |
| Supermarkets and Retail Floors | Promotions run to a calendar and the artwork lands ready to go up. Changing a print in place, on a shop floor, in trading hours, is the difference between a campaign starting on Monday and starting whenever somebody has time. |
| Council Buildings and Public Offices | Statutory notices, service information and consultation posters have to be displayed properly and kept current. A wall frame gives that content a permanent home, rather than a fresh strip of tape and another set of curled corners each time. |
| Gyms, Leisure Centres and Pools | Class timetables, safety instruction and membership offers all go on walls that are wiped down often. Aluminium and a cover sheet hold up in that air far longer than paper taped to tiling, which curls at the corners inside a fortnight. |
| Transport Hubs and Waiting Rooms | Timetables, service updates and directions get read by people who are already anxious about missing something. Large print at eye level, held flat and free of glare, answers the question before anyone has to ask at a desk. |
The A1 black snap frame uses the same profile, the same front-opening sides and the same mitred corners in a smaller format, which suits doorways, lift lobbies and the spaces between windows where a large frame will not fit.

Changing a poster in a public building is usually a two-person job. The frame comes off the wall. One person holds it while the other works the back off, the print gets swapped, then the whole thing goes back up and has to be levelled again. This frame opens where it hangs. Press the four sides and they lift, lay the new print on the board, press the sides shut. The fixings are never touched and the frame never moves. A receptionist can do it between visitors, which is often the difference between artwork going up the day it arrives and going up the following week. The same applies at the other end of a campaign, when a poster has to come down at short notice because the offer has closed or the guidance behind it has changed.
Corridor lighting is hard on paper. Strip lights throw a white band across a bare print, and anyone reading from the side sees the reflection rather than the words. The cover sheet breaks that light up so the message stays legible from an angle. It also presses the poster flat against the board behind it. That matters over a long run, because a print left loose in a frame ripples as a room warms and cools through the day, and a rippled poster starts to look tired well before the campaign it carries has finished. Held flat behind a cover, the same sheet comes through a full season looking as it did on the morning it went in.
Look at the corners of a large frame and you can see how it was put together. These four lengths are cut at an angle, so each corner closes as one continuous line rather than a visible step. The lengths themselves are aluminium, so a frame this wide holds a straight edge from one corner through to the next. On a reception wall or a corridor people walk every day, those two things decide whether a frame looks finished. Nobody stops to admire a mitred corner. They do notice when a building looks cared for, and the corners are a good part of why.
Getting it on the wall is a one-person job. The frame is light for something this large, so it can be held up and levelled while the fixing holes are marked, with no second pair of hands and no bench to lay it on first. Orientation is settled at that moment too, because the frame is symmetrical and works either way round. Screws and plugs come in the box for masonry and plasterboard. Hollow walls and clad surfaces are the exception and want anchors rated for that substrate, which is worth settling before the first hole goes in.
Where several walls need covering, the A0 black snap frame comes as a pack of five on the same profile and the same front-opening sides, which works out more sensibly than ordering singly across a building.
Ring us on 01279460460 or send over the wall list and we will work out the sizes.
SF3040B is a large format black snap frame for 30 x 40 inch posters, supplied by Displaysense. All four sides hinge open at the front so prints are changed with the frame still fixed to the wall. Overall size 793mm x 1047mm x 11mm. Weight 2.75kg. Anodised aluminium profile of 25mm with mitred corners, finished in black. Supplied with an anti-glare cover sheet, a backing board and wall fixings. Mounts portrait or landscape for indoor use. Specified for NHS receptions, waiting areas, school and college corridors, retail floors, council buildings, leisure centres and transport hubs. A0 and A1 formats in black are also stocked. Displaysense, UK display specialist based in Hertfordshire since 1978.
Full specification for the SF3040B, a 30 x 40 inch black poster snap frame. Poster size and how the frame opens come first, then the cover and the profile, then the measurements, the weight, the finish and the mounting. Every line carries a short note explaining what that figure means in practice once the frame is up on a wall.
| Specification | Detail | What This Means for You |
|---|---|---|
| Poster Size | 30 x 40 inches | Large format, sized so a standard print drops straight in without trimming, and without a gap showing round the edge of the artwork once the sides are closed. |
| Opening | All four sides hinge open at the front | Prints change with the frame still screwed to the wall, so nothing has to be lifted down, taken apart or levelled up again once the new artwork is in. |
| Cover | Anti-glare sheet over the print | Scatters overhead lighting instead of throwing it back in one band, and holds the poster flat against the backing board so the paper cannot ripple over time. |
| Frame Profile | 25mm, mitred corners | A defined border round the artwork, with the four lengths cut at an angle so each corner closes as a single continuous line rather than a visible step. |
| Frame Size | 793mm wide x 1047mm high x 11mm deep | Barely stands off the surface at all, which keeps the frame clear of passing trolleys and well out of the way in a narrow corridor. |
| Weight | 2.75kg | Light enough for one person to hold flat against the wall while marking out the fixing points, with no need for a second pair of hands. |
| Material | Anodised aluminium | Holds a straight line across a long edge. At this size that matters, because any bow in the middle lets the cover lift and the print start to curl. |
| Finish | Black | A dark border lifts artwork off a magnolia or white wall, and everyday marks show far less on black than on a bright or polished finish. |
| Orientation | Portrait or landscape | Decided at the point of drilling, so a single frame suits either way round and a wall of them can run in mixed directions to fit the artwork. |
| Mounting | Wall fixings supplied | Screws and plugs are included for standard masonry and plasterboard. Hollow or clad walls want anchors rated for that substrate instead. |
| Environment | Indoor | Built for interior walls in receptions, corridors and shop floors. For a sheltered or fully exposed outdoor position, choose a case built to keep weather off the print. |
| Also Available | A1 and A0 in black | Smaller formats on the same profile, suiting doorways, lift lobbies and the strip of wall between windows. Both are supplied in packs rather than singly. |

A frame holds the print, but height, position and the wall it goes on decide how many people actually read it. Choosing between a frame, a holder and a case comes down to who needs access and how often. These four Displaysense guides cover picking the right display for the job, hanging posters where they actually get seen, and why printed material still holds its own on a wall in 2026.

"I wasn't sure if I had ordered the right type of holder, but it's exactly what we wanted and more. Nice and simple to install - we just used some double sided sticky pads (but you can also screw to wall with screws provided). Also easy to change for our conservation day fundraisers."
