Lock in the highest level of projector security with the PE1120. Solid 1/2" diameter steel bars provide protection from theft or accidental damage. Installation is a snap - just snap the two halves of the steel frame together and hook the enclosure body to the frame. It's so easy that you can attach it to existing multimedia projector installations without having to remove the projector mount or disturb the image alignment settings. It's the toughest security available with a user-friendly design.
