Tamper-proof snap frames provide the most security for your marketing literature materials. These tamper-resistant snap frames are designed to display A4, A3 and A1 posters and can be mounted in a portrait or landscape position. Using an anti-tamper lever key, the four sides of the frame snap open and shut, allowing you to change the literature whilst still fixed to the wall. Whether you’re looking for a tamper-proof snap frame or an anti-tamper lever key, you’ll find everything you need here at Displaysense.
