A clean, functional shower curtain hook designed to clip directly onto a 28mm cylindrical shower rod - no tools, no screws.

The clip snaps on from the bottom with a two-arm flex mechanism: one rigid arm (4.8mm) and one flexible arm (2.5mm) provide secure retention while still allowing easy removal. The bore uses a toroidal profile - crowned at 30mm, opening to 32.4mm at the faces - which eliminates the drawer-lock binding effect that flat-bore designs suffer when the hook tilts under load. The hook opening is sized for ~6mm curtain eyelets and fits standard off-the-shelf shower curtains.

Compatible with most 28mm diameter metal or plastic shower rods.
