The patented, built-in clamps rigidly hold AC, MC, MCI-A and even NM cable, from 14/2 to 10/3 (plus ground)—all on one side of box, for easy wire dressing. Clamps and grounds are attached with forward-facing threaded studs—nothing protrudes out the back. “Superneutral” multi-circuit feeds can now be used to cut home runs and panel entries by two-thirds.
 
Homepage Uses
The 2-gang Grady Box replaces standard 4x4 and 2-gang boxes, eliminates plaster rings and cable connectors, reduces installation time by about 10 minutes per box (more than paying for itself), cuts cable runs up to 60% and produces a superior finish (outlets rest firmly on steel, not loose on drywall). It also addresses ground security concerns with MCI-A connectors, and cables like Southwire’s excellent MC-AP.
