What Is a J Clamp?

A J Clamp is a metal or plastic fixing clip shaped like the letter “J”. It’s designed to hold, fasten, or secure objects together, usually by hooking over an edge or flange.

Common uses include:

• Securing roofing sheets and panels

• Attaching cable trays or conduits

• Fixing fencing and mesh panels

• Supporting pipework or ductwork

• Temporary holding during construction or assembly

2. Open the clamp wide enough for your workpiece.

3. Position the jaws on each side of the material.
