The Chief CMS394 is a 24-inch (609 mm) dual joist ceiling mount, a structural adapter that bridges two ceiling joists so the projector or display attachment point does not have to fall directly under a single joist. In wood-framed ceilings, the ideal projector location often lands between framing members; this adapter fastens across both joists and lets the column connection be set where the image geometry needs it, rather than where the framing happens to be. That added placement freedom can reduce the need for keystone or digital image correction. The adapter is rated for 400 lbs (181.4 kg), sits a low 1.9 inches (48 mm) deep, and is finished in black. It integrates with Chief's CMS extension columns and ceiling mounts. Chief lists it as TAA compliant. Fasteners suitable for the joists, column and mount are sourced or sold separately; confirm joist spacing before ordering.
