Over-Door Towel And Robe Hook
A clamping over-the-door double hook for wet towels and robes on a bathroom door: the 38 mm throat and 2.4 mm flexure tongue are squeezed by an M4 screw in a 5.5 mm heat-set bore, so it locks to any 32–38 mm door (a standard 1-3/8 in / 34.9 mm interior door sits mid-range) instead of swinging and scuffing paint. The bridge over the door top is only 3.2 mm thick so the door still shuts, the strap is 22 mm wide, and the part is 82 x 95 mm overall with a robe hook 36 mm down and a deeper towel hook at 82 mm.
