Product information

Description

The Chief Decorative Ring CMA640B with a 1.9-inch inner diameter in black is designed to enhance projector mount setups utilizing CMS and CPA fixed and inner adjustable columns. This accessory conceals gaps and joints around column installations, providing a clean, professional aesthetic finish for both commercial and residential audio-visual environments.

Advantages

This decorative ring features a hinged design that allows it to open easily for straightforward installation around existing setups. It visually improves suspended ceiling installations by neatly covering the hole where the extension column passes through the ceiling tile, ensuring a polished and uniform appearance throughout the room.

Suitable for

  • Concealing ceiling penetration gaps in suspended ceiling installations
  • Professional AV installations in commercial and residential environments
  • Projects utilizing Chief CMS and CPA fixed and inner adjustable columns

This ring may not be suitable for columns with dimensions outside the 1.9-inch inner diameter specification or for use with extension systems from manufacturers other than Chief, where proper fit and compatibility cannot be guaranteed.

Key specifications

  • Brand compatibility: Chief
  • Column compatibility: CMS and CPA fixed and inner adjustable columns
  • Inner diameter: 1.9 inches
  • Product colour: Black
  • Width: 91.4 mm
  • Depth: 91.4 mm
  • Height: 5.08 mm
  • Package weight: 36.29 g
  • Maximum weight capacity: 113.4 kg

To use the decorative ring, open the hinged ring structure and position it around the installed extension column at the ceiling surface. Close the ring securely to cover the opening in the ceiling tile, ensuring a snug fit against the column and the ceiling surface for an even, finished look.

What to consider before purchase

  • Verify that your existing column setup uses Chief CMS or CPA fixed or inner adjustable columns
  • Confirm that the column inner diameter matches the 1.9-inch specification of the ring
  • Check the ceiling tile opening size to ensure the outer dimensions of the ring will adequately cover the gap
For optimal aesthetic results, install the decorative ring only after the projector mount and extension columns are fully secured and adjusted into their final positions.
