Fixed Extension Column for Projector Mounts

The Chief CMS003 is a 3-inch fixed extension column designed to lower a projector from the ceiling. It suits installers who need a short, rigid drop in commercial or residential AV setups. The column supports loads up to 500 lbs and is finished in black.

Verify 1.5-Inch NPT Thread Compatibility

Before ordering, confirm that your existing ceiling plate or projector mount uses a 1.5-inch NPT thread on both ends. This column threads directly into Chief 1.5-inch NPT components. It will not fit mounts with different thread sizes or proprietary quick-release interfaces.

Adds 76 Millimetres of Fixed Drop Length

The column provides a permanent 76.2 mm extension between the ceiling plate and the projector mount. It does not telescope, swivel or include cable management features. The aluminium construction adds structural strength without adjustable positioning.

Questions about this item

What comes in the box and what else do I need to buy?

The box contains the 3" (76 mm) black aluminum extension column with 1.5" NPT threads on both ends. You must purchase a compatible Chief 1.5" NPT ceiling plate or other accessory separately to complete the installation.

Which length or finish should I choose for my setup?

This model is a fixed 3" (76 mm) column in black; silver and white finishes are also available. Select the colour that matches your ceiling hardware and choose a different column length if you need more or less drop.

What does the 500 lbs (226.8 kg) weight capacity mean for my projector?

The column is rated to support up to 500 lbs (226.8 kg), so it will safely hold virtually any commercial projector when paired with a properly rated Chief ceiling plate and structural anchor.
