Self releasing geared clamp hook for (US) Iron Pipe

Modified the HD_Creator's original “Self releasing geared clamp hook for towels" for mounting onto US ¾" Iron Pipe (OD 26.67 mm).

I shortened the “herring gear for glue plate” and added it to a simple 5mm threaded pipe clamp for attaching to the vertical iron pipe that is common for industrial looking desk and shelving (at least in the US).

NOTE: Original idea and gear design came from HD Creator. The Iron Pipe clamp is original.
