Concentrically Loaded Joist

The Steel Joist Institute recommends hanging loads from joist chords concentrically to avoid the possibility of torsion on the chord. Installers no longer need to create a make-shift way to accomplish this. The MCL Hanger was designed to place the hanger and threaded rod in the gap between the joist chord angles, thus hanging concentrically from either the top or bottom chord. By design, as the hanger is tightened to the joist it will not rotate.
