I took an original one off and traced it on a 1x4, cut it out with a jigsaw and drilled a 5/16 hole about half way through, then a 1/16 hole the rest of the way and attached it with a drywall screw. worked so good I made 6 of them as I have 2 of the 8 gun cabinets. BTW this was after 4 calls and 2 emails to Stack-On. they would never respond.
