Chief CMA-347 Projector Vibration Isolator

Overview

The Chief CMA347 is a projector vibration isolator designed to reduce image movement caused by structural vibrations. It fits between two Chief CMS columns and effectively dampens vibrations from sources like HVAC systems, foot traffic, and nearby road noise. Rated for projector systems up to 35 pounds, this isolator helps maintain steady, clear images in environments where even slight shaking can disrupt presentations or movie viewing.

Key features

• Supports projector systems weighing up to 35 pounds, accommodating a wide range of setups.
• Threads onto standard 1.5-inch NPT Chief CMS columns, allowing easy integration into existing or new installations.
• Includes two sets of springs to fine-tune vibration isolation based on the projector’s weight for optimal performance.
• Patented internal design provides effective damping without the need for ongoing adjustments after installation.
• Reduces vibrations caused by common building disturbances such as HVAC equipment, foot traffic, and passing vehicles.
• Compatible with various Chief mounts and extension columns, offering flexible placement options.

Key specs

• Maximum supported load: 35 lb (15.9 kg)
• Thread size: 1.5-inch NPT (National Pipe Thread)
• Includes two spring sets for load adjustment
• Designed for use with Chief CMS columns

Installation and setup

Installation is straightforward, as the isolator simply threads between two Chief CMS columns. This design allows you to position the isolator anywhere along an existing projector drop or incorporate it into a new mounting system. Once installed, the internal damping mechanism works automatically, eliminating the need for manual tuning or maintenance.

Ideal uses and environments

This vibration isolator is well suited for classrooms, boardrooms, home theaters, and other spaces where image stability is critical. It is especially beneficial in buildings affected by vibrations from rooftop air handlers, nearby subway lines, upper-floor gyms, or heavy foot traffic. By isolating the projector itself, it offers a practical solution that avoids the complexity of addressing every vibration source in the building.
