Snaps onto common 4-gauge scan hooks (sold separately) with a self-centering hole. Clear window provides a clean appearance while protecting data tickets or UPC inserts. Scan codes through the clear facing or stick adhesive labels to the front. As a bonus, gripper fins along the top edge allow thin signs to be held outside the window.
Designed to fit common 4-gauge hooks (0.212" to 0.225" dia.)
