Our patented STAS zipper hook is now offered with a theft delaying bracket. Still easy to use and simple to adjust, the Zipper Pro is ideal for public spaces or where security is a concern. The bracket does not permit the artwork to be simply lifted off of the hook. The security bracket will also hold the artwork firmly in place, so if the picture frame is accidentally bumped it will not fall off of the hook onto the floor. With STAS zipper pro hooks you can hang your paintings, photo frames and other wall decorations perfectly. The zipper pro hook is so simple to adjust that you can hang your decorations at the right height in an instant. Press the side button to adjust the height then release the button and the hook automatically locks in place. The Zipper Pro hook in combination with the perlon cord can bear a load of up to 33 lbs per hook, in combination with the steel cable it can bear a load of up to 44 lbs per hook.
