The Chief CMA273 Extension Column Threaded End Cap covers the open end of a 1.5-inch NPT extension column. Columns are often cut or installed so that a threaded end is left exposed, for example above a structural attachment or where a column passes through a ceiling, and the CMA273 screws on to hide the raw threads and give the installation a finished appearance. Measuring 1.4 by 2.5 by 2.5 inches, it adds minimal height and matches Chief's black column hardware. Because it threads on rather...

Chief Quick-Snap Cable Covers solve a common problem on projector and display columns: cables that cannot, or should not, be pulled through the inside of the pipe. The CMA274 lets installers run HDMI, network and power cords along the outside of the extension column and then snap a cover over them, so the finished install still looks clean. The snap-on design goes on without tools and saves time compared with fishing cable through the column. Covers adapt to both 1.5-inch and 2-inch NPT...

The Chief CMA278 is a 10-pack of vinyl end caps for extension columns. Each cap slips over the open end of the pipe to hide cut edges and threads, giving exposed column ends a neat, consistent finish. Unlike a solid threaded cap, the CMA278 is pre-cut so projector or display cables can still pass through the cap and exit the column, which makes it useful at the top of a column above a ceiling plate or at any end where wiring leaves the pipe. The soft vinyl presses on without tools, and buying...

The Chief CMA290 is a pack of ten wire suspension locks for hanging equipment from flexible wire rope instead of rigid pipe. Each lock uses a one-way clamp that lets the wire feed through in one direction and grips it against the load, while a quick-release lever lets the installer reposition or level the hung device. The locks accept 0.13-inch (3 mm) or 0.19-inch (5 mm) diameter wire rope, and Chief rates them at 250 lbs on the smaller wire and 640 lbs on the larger. Wire suspension is useful...

The Chief CMA330 is an 8-inch square offset ceiling plate for 1.5-inch NPT extension columns. On a flat ceiling a standard plate sits tight against the surface, leaving nowhere for cables that run inside the column to exit. The CMA330 raises the column connection 1.75 inches off the mounting surface, creating a gap so projector power and signal cables can travel up through the column and out the top of the plate before continuing to the equipment rack or wall. The result is a clean...

On a flat ceiling a standard plate sits tight against the surface, leaving nowhere for cables that run inside the column to exit. The CMA330-G raises the column connection 1.75 inches off the mounting surface, creating a gap so projector power and signal cables can travel up through the column and out the top of the plate before continuing to the equipment rack or wall. The result is a clean...

The Chief CMA340 Projector Stabilization Kit adds lateral bracing to long extension columns. Tall drops are prone to swaying from HVAC airflow, building movement or contact, and that motion shows up as a shaking image on the screen. The CMA340 clamps to a 1.5-inch NPT column and runs four cables out to the surrounding structure, where turnbuckles let the installer tension each line until the column is held firmly in place. The kit contains one pole clamp, four 10-foot cables and four...

The Chief CMA345 Structural Ceiling Plate pairs a ceiling attachment with a flexible joint. A neoprene rubber element between the plate and the column connection absorbs shock and dampens vibration traveling from the building structure into the column, which helps keep a projected image steady when HVAC equipment, foot traffic or nearby machinery shake the ceiling. The plate is also offset from the mounting surface, so cables running inside the column can exit above a flat ceiling rather than...

Building vibration from HVAC equipment, footsteps, nearby traffic and closing doors travels down a projector's column and shows up as a jittery image. The Chief CMA347 Vibration Isolating Coupler sits in line between two Chief CMS 1.5-inch NPT columns and isolates the lower column, mount and projector from much of that movement. Chief designs it for suspended systems under 35 lbs, where system weight means everything hanging below the isolator: the lower column, the projector mount and the...

The Chief CMA348 is the large-venue member of Chief's vibration isolating coupler family. Installed in line between two Chief CMS 1.5-inch NPT columns, its patented design limits the vibration that passes from the building structure into the lower column, so large-venue projectors hold a steadier image when HVAC equipment, crowds, road traffic or doors shake the ceiling. It is designed for suspended systems from 35 to 100 lbs, counting everything below the isolator: the lower column, the...

The Chief CMA348W is the large-venue member of Chief's vibration isolating coupler family. Installed in line between two Chief CMS 1.5-inch NPT columns, its patented design limits the vibration that passes from the building structure into the lower column, so large-venue projectors hold a steadier image when HVAC equipment, crowds, road traffic or doors shake the ceiling. It is designed for suspended systems from 35 to 100 lbs, counting everything below the isolator: the lower column, the...

The Chief CMA351 Heavy Duty Swivel Adapter adds controlled rotation to an extension column run. Installed in line between two columns, it lets the lower column, mount and projector rotate smoothly through up to 330 degrees, and adjustable stops let the installer set the swivel range so the projector can only turn as far as needed. That makes it a practical solution for rooms that project onto more than one wall, such as multipurpose rooms, training spaces and divisible meeting rooms, without...

The Chief CMA360 I-Beam Clamp attaches a projector or display column directly to exposed steel. It clamps onto an I-beam or truss flange from 4 to 12 inches wide and provides a 1.5-inch NPT connection for a vertical extension column, so installers can hang equipment from the building's steel without drilling, welding or adding unistrut. That speeds installation in warehouses, gymnasiums, arenas, retail spaces and other open-structure buildings, and it keeps the steel intact for future changes....

The Chief CMA362 C-Clamp is a universal structural adapter for hanging presentation equipment from pipe, truss or lumber. It grips structures up to 2.75 inches in outside diameter, including standard 2 x 4 framing, and provides an opening for a 1.5-inch NPT extension column that drops vertically to a projector or display mount. Cables can be routed through the column for a tidy finish. Because it clamps on rather than bolting through, the CMA362 installs quickly and leaves no damage, which...

The Chief CMA365 Truss Ceiling Adapter connects a 1.5-inch NPT extension column to truss. It works with square, round, rectangular and I-beam style members up to 3 inches (76 mm), so one part covers most of the truss and grid profiles found in theaters, studios, event spaces and exhibit structures. Once the adapter is fastened to the truss, the column threads in and drops to the projector or display mount. Chief rates the adapter at 250 lbs and lists it as UL Listed. It measures 6 x 5.4 x 5.4...

The Chief CMA366 Architectural Spanning Adapter lets you hang a projector or flat panel mount from exposed truss, pipe grid or similar overhead structure where there is no solid ceiling deck to bolt into. Instead of attaching to a single member, the adapter spans across two parallel chords and clamps to each one, creating a centered, load-rated attachment point for a 1.5-inch NPT extension column.The clamps grip round tube up to 2 inches outside diameter or square tube up to 1.9 inches, and...

The Chief CMA370 Unistrut Adapter is a small hardware kit for installers who need to fasten a Chief ceiling plate to strut channel instead of directly to wood or concrete structure. Many commercial ceilings use Unistrut or similar 1-5/8 inch (41 mm) channel to bridge between beams or to create an attachment grid, and this kit gives you the spring-loaded channel nuts and bolts to lock a Chief plate onto that channel securely.The kit includes four 0.38-inch (10 mm) channel nuts with springs,...

The Chief CMA372 Offset Unistrut Adapter attaches an extension column straight to 1-5/8 inch (41 mm) Unistrut or U-channel without a separate ceiling plate. It is a compact, heavy-duty fitting rated by Chief for 500 lbs, intended for structural ceilings where strut channel is already in place or is the easiest way to span framing.Its offset body is what sets it apart: rather than forcing cables to exit the column below the ceiling, installers can run wiring up through the column and out the...

The Chief CMA380 Concrete Fastener Kit supplies the anchors needed to secure a Chief ceiling plate or projector mount to solid concrete or brick. Mounting into masonry calls for different hardware than wood joists, and this kit gives installers a matched set of four fasteners from Chief rather than leaving them to source anchors on site.Chief lists a 250-lb rating for the kit, consistent with its standard ceiling plates. Use it wherever a projector, extension column or ceiling-hung display...

The Chief CMA385 Internal Joist Mount solves a common retrofit problem: the spot where the projector or display needs to hang falls between two ceiling joists rather than on one. The mount installs inside the joist bay and extends to bridge the gap, giving you a solid, centered attachment point without adding blocking or relocating the equipment.Its length adjusts from 14.1 to 22.75 inches, so it can fit a range of joist spacings, and Chief rates it at 300 lbs. The overall profile is just 4.1...

The Chief CMA395 Angled Ceiling Plate is built for projector installations under sloped, vaulted or cathedral ceilings. Bolting a standard flat plate to an inclined surface leaves the column and projector hanging off-vertical; this plate compensates for the slope so the extension column or mount drops straight down and the projector image stays square on the screen.Despite its small footprint of 4.4 by 3.4 by 7.5 inches, Chief rates the plate at 500 lbs, giving plenty of margin for a column,...
