Our Allen Key Lockable Snap Frames provide secure, tamper-proof poster display for high-traffic areas. Designed for A1, A2, A3, and A4 posters, these frames are locked via a discreet hexagonal screw on one side, preventing unauthorised opening.

The other three frame sides are interlocked so they cannot be opened until the locked side is released with the supplied Allen key. Perfect for protecting posters in public spaces, transport hubs, retail stores, schools, and community venues.

Each frame comes with hidden wall fixings for a neat installation and a clear protective cover to shield your poster from dust, moisture, and UV light.
