Chief CMA351

The Chief CMA351 is a heavy-duty swivel adapter designed for professional projector ceiling installations where flexibility is critical. Built for multi-wall projection environments, it connects two standard 1½" NPT threaded extension columns and delivers smooth, safe axis rotation across a 0–330° range with settable stop positions. Rated for an exceptional 226,8 kg load capacity and constructed entirely from steel, this adapter is engineered for demanding commercial AV environments. Certifications including TÜV, UL Listing, and TAA compliance make it suitable for institutional and government installations. With a 10-year warranty and a simple, tool-friendly installation process, the CMA351 is the go-to solution for integrators who need a reliable, permanent mount that can still rotate a projector to cover more than one projection surface.

330° Swivel with Settable Stop Points

The CMA351 allows axis rotation across the full 0–330° arc, and stop positions can be set at any point within that range using the included hardware. This matters in practice because a projector in a conference room or multi-purpose venue often needs to cover more than one wall or screen surface without dismounting or re-aligning. Once the stops are set, users can rotate the projector confidently between positions, knowing it will land exactly where calibrated — no guesswork and no need to call an integrator back for readjustment. This makes it a particularly capable solution for boardrooms, training facilities, and large classrooms that routinely reconfigure for different presentations.

226,8 kg Load Capacity for Large-Venue Projectors

With a rated load capacity of 226,8 kg (500 lbs), the CMA351 is built to handle the largest and heaviest large-venue and installation projectors on the market. For integrators, this means a single adapter SKU covers virtually every projector install without needing to check load compatibility. For end users operating high-stakes environments — auditoriums, houses of worship, simulation rooms — the overbuilt rating delivers peace of mind that the mount will hold securely for years without fatigue or creep, regardless of vibration or environmental factors.

One mount. Every wall. 330° of projection freedom.

Standard 1½" NPT Compatibility with Cable Access

The CMA351 attaches directly to standard 1½" NPT threaded extension columns — the industry-standard thread size used across Chief's full column ecosystem and by most other professional projector mount manufacturers. This ensures the adapter integrates cleanly into new or existing ceiling mount assemblies without adapters or custom threading. Cable routing is also built in, so signal and power cables can be routed neatly through the assembly and hidden from view. The result is a clean, professional install with no exposed cabling — an important factor in boardrooms and customer-facing environments.

TÜV, UL and TAA Certification for Institutional Installs

The CMA351 carries TÜV certification, UL Listing, and TAA compliance. TÜV and UL certifications confirm that the product has been independently tested for structural and electrical safety — a requirement for many institutional procurement processes. TAA compliance (Trade Agreements Act) means it qualifies for US federal government and many state and local government procurement programmes. For integrators working in education, government, defence or healthcare markets, this removes a common procurement hurdle and means the CMA351 can be specified on compliant bids without substitution.

10-Year Warranty and Complete Hardware Kit

Chief backs the CMA351 with a 10-year parts and labour warranty — one of the strongest in the projector mount category. The package ships with all hardware needed for installation, including the swivel adapter plate, stop plate, nylon washers, Nylock nuts, allen screws of multiple sizes, and two allen wrenches. Having everything in the box removes the installer's dependency on sourcing metric or imperial fasteners separately, which is a practical time-saver on-site. The long warranty also reduces total cost of ownership for end users running permanent installations where replacing or re-purchasing hardware would mean ceiling access and scheduling.
