Chief CMS261W 1 1/2 NPT Cutoff Thread Adapter | Mounting Adapter

Finish suspended AV installs with a threaded adapter built for clean mechanical integration. The Chief CMS261W provides a 1 1/2 NPT cutoff thread interface for connecting compatible ceiling-mounted hardware in commercial environments where fit, alignment, and installation consistency matter. This adapter is designed for integrators who need a dependable transition point between threaded pipe and the rest of the mounting assembly. In multi-room deployments, education spaces, conference areas, and other fixed AV environments, that kind of detail helps reduce installation friction and keeps the final assembly aligned with the rest of the system. Because it is a purpose-built mounting accessory, the CMS261W supports a more controlled install than improvised hardware substitutions. That matters when the mount must sit correctly, remain serviceable, and present a clean finished look above the room. For projects where labor time and installation quality both affect total cost, a dedicated adapter is the right choice.
