Pantry Shelf Can Fence Label Clamp
A 50 mm wide clamp that fits over the front edge of a pantry or cabinet shelf. It adds a 30 mm fence so cans and jars can't roll off, and has a slide-in label channel (1 mm slot, 22 mm visible window) on the front. The jaw opens to 20 mm and an M4 thumb screw in a heat-set insert from below tightens it, so it fits any shelf from 12 to 19 mm thick (5/8 and 3/4 in melamine or plywood) with no drilling.
