Chief - Legrand CMS012 Fixed Extension Column Ceiling Mount

Product Description

The CHIEF - LEGRAND CMS012 is a fixed extension column designed for ceiling mount display and projector installations. Constructed from aluminum, this column provides a rigid, stable vertical drop from a ceiling plate to a mounted display or projector head. It is rated to support loads up to 500 pounds, making it suitable for heavy commercial AV equipment. Installation is typically performed by AV integrators or commercial electricians working within structured ceiling systems. The aluminum construction keeps weight down while maintaining structural integrity across a range of overhead mounting applications.

This fixed extension column is used in commercial and institutional environments where a ceiling-mounted display, projector, or AV component requires a set vertical offset. Typical applications include conference rooms, classrooms, auditoriums, and retail spaces where ceiling height demands a defined drop length. The fixed design means the column length is set at the factory and does not adjust in the field, so correct drop measurement is required before ordering.

Installation Notes

Installation should be performed by a qualified AV integrator or licensed contractor familiar with structural ceiling systems. Before installation, verify that the ceiling structure can support the combined weight of the column, mount, and display equipment. De-energize any electrical systems in the work area before drilling or fastening into ceiling assemblies. Follow all applicable local building codes and manufacturer torque and fastener specifications for the ceiling plate hardware used with this column.
