Tension Pole Caddy Screw-Lock Shelf Stop
This is a replacement shelf stop for telescoping shower caddy poles from 16 to 32 mm in diameter, for when the shelf's plastic locking tab breaks. An M5 screw runs through a captured M5 nut and pushes the pole into a 90° V-jaw, and the shelf sleeve rests on the 58 x 42 x 16 mm collar. Slide it onto the pole from the bottom end, set the height and tighten an M5 x 35–40 mm screw.
