The MJC Multiple Joist Connector allows two I-joists/metal web joists to be fixed together to act as a single unit, transferring the incoming load from the loaded ply to the unloaded ply.

The MJC is an improved solution to the traditional filler block detail, which historically has been time consuming to fit and difficult to check if fitted correctly. It’s simple and effective design allows one size of product to be used on any joist size – regardless of height or width.
