Key Features

1.5 in NPT thread adapter
Adds 2 in to installation height
Designed for cut Chief extension columns
Includes set screws and bolts
Column cutoff accessory
Chief CMS261 model

Restore a proper threaded termination after cutting an extension column with the Chief CMS261 cutoff thread adapter. Built for commercial AV installations, it adds 1.5 in NPT threads to a Chief extension column that has been cut to a shorter length, helping preserve compatibility with the rest of the mounting system. The adapter adds 2 in of height to the installation and includes set screws and bolts for security and stability. That matters when the mount has to feel finished, align correctly, and hold up under the demands of a professional deployment. Instead of improvising a field fix, integrators get a purpose-built accessory that helps keep the installation clean and mechanically sound. For projects where columns are trimmed on site, the CMS261 helps maintain a proper threaded connection without compromising the overall system design. It is a practical detail, but in AV infrastructure, details like this are what separate a workable install from a polished one.

Ideal For

Finishing a shortened extension column in a commercial AV install
Restoring threaded compatibility after on-site column cutting
Supporting projector or display mounting systems that use Chief columns
Cleaning up field modifications in conference rooms and public spaces
