Chief CMA360

The Chief CMA360 is a structural I-beam clamp adapter designed for professional AV installers who need to suspend projector mounts or display columns from exposed I-beam structures. It bridges a standard 1.5" NPT extension column to I-beam trusses ranging from 7,2 to 30,5 cm in width, making it suitable for a wide variety of commercial venues — lecture halls, houses of worship, gymnasiums, and event spaces with structural steel ceilings. Built from steel and rated at 113,4 kg load capacity, the CMA360 is fully UL Listed and TAA Compliant, ensuring it meets both safety and procurement requirements for US government projects. It is compatible with Chief CMA Series accessories and RPA Series projector mounts.

Wide I-Beam Compatibility

The CMA360 accepts I-beam flanges from 7,2 to 30,5 cm wide — a range that covers most structural steel beams found in commercial and institutional buildings. This means a single SKU handles everything from smaller secondary beams in conference rooms to the heavy main girders in gymnasiums or houses of worship, without requiring a different clamp for each job. Installers can confidently specify this adapter before site survey knowing it will fit the vast majority of standard structural steel profiles.

113,4 kg Rated Load Capacity

With a certified maximum load of 113,4 kg, the CMA360 supports the full weight of heavy projectors combined with extension columns, ceiling plates, and associated hardware without compromise. This rating is particularly relevant in rental-staging and permanent-installation contexts where multi-pound commercial projectors — including large-venue laser projectors — are used. The steel construction and UL Listing back up the capacity figure with independently verified safety assurance, giving end users confidence in long-term structural integrity.

One clamp. Any I-beam. Full Chief ecosystem compatibility.

UL Listed and TAA Compliant

UL Listing confirms the clamp has been independently tested to recognized safety standards — an increasingly common requirement in commercial and institutional AV bids. TAA (Trade Agreements Act) compliance means the CMA360 qualifies for US federal, state, and municipal procurement contracts where American-made or TAA-designated origin is mandated. For integrators working on government buildings, schools, or publicly funded venues, this compliance eliminates a potential disqualifier at the bid stage.

Compatibility with Chief CMA and RPA Series

The CMA360 is designed as part of Chief's broader CMA Series accessory ecosystem and is directly compatible with the RPA Series projector mounts. This means it slots cleanly into Chief-based system configurations without the need for additional adapters or custom fabrication. For integrators already specifying Chief hardware, the CMA360 is a drop-in structural solution that preserves the same warranty, support, and compatibility chain as the rest of the installation.
