Product Overview
The Chief CMS380 is a truss ceiling adapter that connects a 1.5" NPT threaded extension column to a 2" (51 mm) tube truss. It gives integrators a fast way to hang projectors and flat panels from truss in temporary projection and staging setups. The adapter is designed for rental and staging installation benefits and is compatible with all Chief CMS columns, accessories, and mounts. A trigger-style clamp allows a one-person install with a 250 lb (113.4 kg) safe working load.
Product Description

The CMS380 adapts 1.5" NPT threaded extension columns to a 2" (51 mm) tube truss, making it well suited to temporary projection and flat panel needs in rental and staging environments. A trigger-style clamp lets a single installer attach the adapter to the truss quickly, and the assembly carries a safe working load of 250 lbs (113.4 kg). A built-in cable port provides a clean exit for cabling. The adapter is compatible with all Chief CMS columns, accessories, and projector and flat panel mounts, so it integrates with existing CMS-based hardware. Extension columns are sold separately to match the required drop. It suits broadcast studio, auditorium, and event staging installations. As a Chief commercial-grade accessory, professional installation is recommended. Browse compatible CMS columns and mounts in the Chief collection at Creation Networks.
