Lever Tool for use with 25mm Tamper Resistant Snap Frames. Manufactured in plastic, this is the tool required to open and close our tamper resistant snap frames. These frames provide secure framing. The snap frame tool simply slides under the edges of the snap frame and you then pull it up to release the clip frame edges. Secure or tamper proof snap frames offer a low-cost vandal resistant solution to displaying posters in public areas. The tamper resistant snap frame offers a snap action poster change convenience with restricted access to non-authorised users. Trying to open a secure snap frame without this product is hard and will prevent casual tampering.
