Chief 1.5" NPT Threaded Column to 2" Tube Truss Clamp

The Chief CMS380 is a truss clamp that lets you fasten any 1.5 inch NPT threaded extension column to a 2 inch tube truss. It is designed for technicians who need a dependable way to hang projectors or flat panels in temporary venues such as rental stages, trade-show booths, houses of worship, or corporate events.

A trigger style latch keeps the clamp open until you are ready to lock it, so one person can position the column, squeeze the handle, and secure the mount without an extra pair of hands. Once tightened, the clamp supports up to 250 lb (113.4 kg), giving you a generous safety margin for heavier displays.

The integrated cable port guides power and signal lines through a smooth opening, which helps prevent pinched cables and keeps the finished installation tidy. Because the CMS380 works with every Chief CMS column and with the full range of Chief projector and flat panel mounts, it fits neatly into an existing kit or growing rental inventory. Extension columns are sold separately.

The body measures 10.18 in × 4.09 in × 2.38 in and comes in black and silver, matching most truss hardware while standing up to repeated setups and tear-downs.
