The Light Source 1/2 inch Pipe to 1/2 inch Bolt Adapter（ライトソース） [新品]

This adapter allows you to use readily available 1/2" steel water pipe to make custom length hanging adapters. The square shape allows you to tighten these to the pipe with a crescent wrench instead of a pipe wrench. The adapter is made from aircraft grade aluminum.
