Lockable Poster Snap Frames: Secure & Tamper-Proof
Protect your message in public spaces. Displaysense offers the UK's leading range of lockable poster cases. Designed for high-traffic environments like schools, train stations, and shopping centres, these frames feature a secure locking mechanism that prevents unauthorised access. Unlike standard snap frames, a secure snap frame requires a specific tool or key to open, ensuring your posters stay safe from vandalism and tampering.
Available in all standard paper sizes from A4 to A0, our range includes both indoor lockable frames and waterproof outdoor poster cases. With reinforced aluminium profiles and high-clarity covers, they offer the ultimate balance of visibility and protection.
Tamper Proof Locking
Stop unauthorised access. Our frames use a sequential locking system or require a specialist Allen key to open. This prevents passers-by from flipping open the edges and removing your poster.
Weatherproof Options
Built for outdoors. Our waterproof poster cases feature an internal rubber gasket seal. This creates a barrier against rain and condensation, keeping your outdoor advertising dry and readable.
Vandal Resistant
Tougher covers. We use high-grade UV-stable PVC covers that are thicker than standard sheets. This protects your poster not just from sun fading, but also from scratches and graffiti attempts.
All Paper Sizes
A fit for every notice. From small A4 lockable frames for toilet cleaning rotas to massive A0 secure frames for cinema posters, we stock every standard size you need.
Versatile Mounting
Install anywhere. All frames come with pre-drilled holes hidden inside the frame. They can be mounted securely to walls in either Portrait or Landscape orientation.
Reinforced Profile
Extra strength. Secure frames typically use a wider 32mm aluminium profile. This makes the frame harder to pry open without the correct tool and provides a more robust border for outdoor use.

Frequently Asked Questions
How does a lockable snap frame work?
Unlike standard frames that snap open by hand, a lockable snap frame uses a special mechanism. Some require a specific Allen key to lever the profile open, while others use a screw-lock system. This prevents anyone without the tool from accessing the poster.
Are they fully waterproof?
Check the model. Our "Waterproof" or "Weather Resistant" range features a rubber gasket seal that makes them suitable for outdoor use. Standard lockable frames are "Tamper Resistant" but may not be watertight, so are best for indoor public areas.
What is the difference between a lockable frame and a poster case?
A lockable snap frame looks like a standard poster frame but requires a tool to open the edges. A lockable poster case is a deeper unit with a hinged door and a key lock, often used for community noticeboards or menus.
Can I buy replacement keys?
Yes. We sell replacement opening tools and Allen keys for our frames. We recommend keeping the tool in a secure place accessible only to staff.
Are these suitable for schools?
Yes. They are the number one choice for schools. They prevent students from defacing notices or removing safety information in corridors, while the rounded corners on many models prevent injury.
What paper sizes do they fit?
We stock all ISO sizes: A4 (210x297mm), A3 (297x420mm), A2 (420x594mm), A1 (594x841mm), and A0 (841x1189mm). Other sizes like 20"x30" may be available in specific ranges.
Do you offer different colours?
Silver is the standard for a professional look, but we also stock Black Lockable Frames which are popular for cinemas, restaurants, and modern office blocks.
How do I mount them?
Just like standard frames, they have pre-drilled holes hidden inside. Because they are often used in public areas, we strongly recommend using screws and wall plugs (supplied) rather than adhesive tape for a secure fix.
