Our tamper resistant poster frames and vandal proof poster frames are perfect for use outside, or wherever undue interference with the poster could be expected. The inner side of the tamper-proof profile fits flush to the protection panel and poster. This prevents fingers from being able to get any purchase underneath the frame to lift it up. To open these frames you need a special strengthened polypropylene opening tool. The tamper proof frame is available in 4 standard sizes, A1, A0, 60"x40" and 40"x30", however we are able to manufacture bespoke size tamper proof frames upon request.
