Product Overview The Chief CMA365 truss ceiling adapter lets integrators mount a projector or display extension column directly to overhead truss structures in auditoriums, houses of worship, and broadcast studios. It connects a standard 1.5" threaded extension column to square, round, rectangular, or I-beam truss up to 3" (76 mm) in diameter. This commercial-grade truss mounting adapter gives AV installers a secure attachment point where conventional ceiling plates will not work. Product Description The CMA365 is engineered for permanent projector and flat panel installations that need to anchor to exposed structural truss rather than a finished ceiling. Its clamp accommodates truss profiles from 0.75" to 3" (19-76 mm) outside diameter, covering the most common truss types found in commercial meeting spaces and event venues. Once clamped, the adapter presents a 1.5" NPT threaded fitting that accepts any Chief 1.5" threaded extension column. This makes it a practical choice for suspending projectors at a precise drop height in rooms with high or irregular ceilings. The adapter is part of the Chief CMS column mounting system, so it integrates with the broader range of Chief extension columns and ceiling hardware. Installers gain a repeatable, code-conscious method for attaching AV equipment to truss in digital signage and large-venue projector applications. The adapter ships ready to clamp, reducing fabrication and custom bracketry on site. For related ceiling hardware, browse the full Chief collection.
