Offset Unistrut adapter for projector ceiling mounts
Chief CMA372
The Chief CMA372 Offset Unistrut Adapter is designed for AV integrators who need to suspend projectors or other ceiling-mounted equipment from Unistrut or U-Channel structural rails. It bridges the gap between standard 4,1 cm (1-5/8") Unistrut systems and Chief's 3,8 cm NPT-threaded extension column ecosystem, accepting any length of standard 3,8 cm NPT pipe threaded at both ends — giving installers the freedom to set the drop height they need. The adapter's offset design routes cables cleanly through a dedicated 3,8 cm gap, keeping wiring concealed inside the pole and out of the Unistrut channel. Ships complete with spring nuts and bolts ready for immediate attachment. UL Listed and TV Certified, with a steel construction rated to carry up to 226,8 kg.

Universal Unistrut Compatibility
The CMA372 mates with all standard 4,1 cm (1-5/8") Unistrut and U-Channel profiles — the most widely used structural rail system in commercial construction. Because Unistrut is already present in many suspended ceilings, schools, houses of worship, and exhibition halls, installers can anchor projectors directly to the existing building fabric without introducing additional steel work. The included spring nuts and bolts mean no extra hardware procurement is needed on site, cutting installation time and the risk of mismatched fasteners.

Integrated Cable Management
A 3,8 cm offset gap is built into the adapter specifically to allow signal and power cables to exit the extension column and transition cleanly into the Unistrut channel above. This is particularly valuable in spaces where exposed wiring is not acceptable — conference rooms, auditoriums, and hospitality venues. Cable routing is handled at the adapter level rather than added as an afterthought, so the finished installation looks professional and is easier to service later without dismounting the projector.
Any Unistrut. Any drop height. Any projector.

Flexible Drop Height via NPT Pipe
Rather than locking the installer into a fixed extension length, the CMA372 accepts any standard 3,8 cm NPT threaded pipe of any length. This makes it straightforward to achieve the precise throw distance and lens height a given projector and screen combination requires — without sourcing proprietary columns of specific fixed lengths. It also means the same adapter can be reused across multiple projects with different ceiling heights, reducing stock requirements for integrators who handle varied venues.

Heavy-Duty Steel Build, 226,8 kg Rated
The adapter is manufactured from steel and certified to carry up to 226,8 kg — far exceeding the weight of any commercial projector currently available. This structural headroom matters in practice: it removes load capacity as a project variable, so the CMA372 can be specified confidently regardless of whether the suspended equipment is a lightweight short-throw unit or a high-lumen large-venue projector. UL Listed and TV Certified ratings provide the documented compliance evidence that commercial installs and facility managers typically require.
