Chief - Legrand CMA100 Ceiling Plate Adjustable Column Mount

Product Description

The CHIEF - LEGRAND CMA100 is a ceiling plate with an adjustable column designed for suspended projector and display mounting applications. This hardware component anchors to a ceiling structure and provides a height-adjustable column drop, allowing installers to position a projector or display mount at the correct working height for the space. It is sold as an individual unit and is typically installed by AV integrators, low-voltage technicians, or commercial electricians performing display infrastructure work.

The CMA100 is suited for commercial and institutional ceiling mount installations where a fixed ceiling plate alone would not provide the necessary drop distance to clear soffits, ceiling tiles, or architectural features. It is appropriate for conference rooms, classrooms, auditoriums, and other venues where ceiling-hung projectors or displays require precise vertical positioning.

Key Features

• Adjustable column drop allows fine-tuning of mounting height to suit the installation environment
• Ceiling plate base provides a stable anchor point to the structural ceiling
• Sold as a single unit, compatible with Chief column-based mounting systems
• Designed for commercial AV ceiling mount applications

Compatibility

Designed as an OEM-style component for ceiling mount column systems used in commercial projector and display installations. Specific compatible accessories or mount heads were not listed in the available product data.

Installation Notes

Installation should be performed by a qualified AV integrator or low-voltage technician familiar with structural ceiling anchoring requirements. Before installation, verify that the mounting surface can support the combined weight of the hardware and the suspended display or projector. Power down any adjacent electrical systems before drilling or anchoring into ceiling structures. Follow all applicable local building codes and manufacturer guidelines for ceiling-mounted display hardware.
