Hook-Ups are adjustable picture hangers that work on wood or metal frames. They attach to each side of the frame to form a secure, wireless, 2 point mounting system that will safely hold up to 100lbs. The patented design allows artwork to be easily leveled with the touch of a finger without removing the item from the wall. The HUS-200 uses a T-screw as the locking device. The HUS-300 uses standard wall fasteners.
