Mounts & Racks

The Chief CMS380 truss clamp adapts Chief's structural column system to 2-inch (51 mm) tube truss, making it a practical choice for rental, staging and event crews who need to hang projectors or flat panels quickly and take them down just as fast. The clamp connects to any 1.5-inch NPT threaded Chief CMS extension column, which in turn accepts Chief projector and flat panel mounts and CMS accessories, so the same mounts used in permanent installs can go on the truss. A trigger-style clamp...

The Chief CMS393 is a 16-inch (406 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...

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...

The Chief CMS440 is Chief's economical Speed-Connect kit for hanging a projector from a suspended (drop) ceiling. The kit's bridge rests above the ceiling tile and clamps to the grid tracks, and the Speed-Connect plate accepts a Chief extension column or projector mount through a hole in the tile, so the tile itself carries no load. It fits standard 2' x 2' and 2' x 4' grids as well as 600 x 600 mm and 600 x 1200 mm metric tile. Per Chief, the kit ships with a 10 ft safety cable, 20 ft strand...

The Chief CMS440N combines Chief's above-tile Speed-Connect suspended ceiling kit with an electrical outlet housing, giving the electrician a defined box location for the projector's power right at the mounting point. The bridge sits above the tile and clamps to the grid tracks, and the Speed-Connect plate takes a Chief column or projector mount through the tile so the tile is not loaded. It suits standard 2' x 2' and 2' x 4' grids, plus 600 x 600 mm and 600 x 1200 mm metric tile. Per Chief's...

The Chief CMS440P2 adds conditioned power to Chief's above-tile Speed-Connect suspended ceiling kit. Along with the grid-clamping bridge and Speed-Connect plate that carry a Chief column or projector mount through the tile, it includes a 2-gang filtered and surge-protected outlet, so the projector plugs in at the mount rather than through an unprotected receptacle. Chief rates the outlet at 15 A and 1875 W continuous and classifies it as a Type 3 surge protective device with a 600 V L-N...

The Chief CMS443 packages the two parts most drop-ceiling projector installs need above the tile: the CMS440 Speed-Connect above-tile suspended ceiling kit and a CMS003 3-inch (76 mm) fixed extension column. The kit's bridge rests above the tile and clamps to the grid tracks, the short column drops through the tile, and a Chief projector mount attaches below, keeping the projector close to the ceiling for low-clearance rooms. The kit fits standard 2' x 2' and 2' x 4' grids as well as 600 x 600...

The Chief CMS445 takes the place of one standard 2' x 2' (600 x 600 mm) acoustic tile in a suspended ceiling grid and provides a Speed-Connect plate for a Chief extension column or projector mount. Because the kit is a complete replacement panel rather than a bridge hidden above an existing tile, it gives a clean, purpose-built look at the projector location and avoids cutting the room's tile. The panel is a low 1.1 inches (29 mm) thick and is rated for a total of 50 lbs (22.7 kg), including...

The Chief CMS446 adapts Chief's above-tile Speed-Connect suspended ceiling kit for pro AV cameras. It is built on the CMS440 bridge with an added camera plate, so a PTZ or conferencing camera can be hung through a drop ceiling without a separate custom bracket. The kit uses a WireVice cable suspension system for quick tie-off to structure and includes an all-point security approach intended to deter theft. Each kit fits 24-inch (600 mm) wide ceiling tile grids. In the box, Chief lists four 25...

Power is handled by a dual-gang housing fitted with a duplex receptacle featuring isolated ground plus surge suppression and multi-stage noise filtering. Because the power...

Sloped drop ceilings are common in lecture halls, auditoriums and stairwell lobbies, and they make it hard to hang a projector or display plumb. The Chief CMS495 solves that by adding an angle-compensating adapter to the Chief CMS440 suspended ceiling kit, so the column and mount below hang straight down even when the ceiling grid is tilted. It accommodates ceilings angled up to 45 degrees and ships with additional support cabling to stabilize the assembly above the tile. The adapter is also...

The Chief CMSHDW Speed Connect Hardware Kit supplies the suspension cables needed to support suspended-ceiling AV hardware from the structure above. It is built around the WireVice cable suspension system: each of the four 25-foot flexible steel cables threads through a WireVice lock that grips the cable and allows quick, adjustable tie-off without crimping or knots. That makes it fast to level a ceiling kit or storage box and easy to make corrections during installation. Use it as replacement...
