Get installations back on schedule with the Chief by Legrand CMS261B Column Cut-Off Adapter — a compact mounting adapter in the Pro Projector Accessories line that restores functionality when a Chief extension column has been trimmed too short. This bolt-on coupler adds 1.5" NPT threads and delivers an extra 2" (51 mm) of usable column height, so you can reattach standard NPT-mount hardware without replacing entire columns.

The black finish minimizes visual impact in ceiling or rack installations, and the durable construction is backed by a 10-year limited warranty for long-term reliability.
