FSR, Inc CB-224S
2ft x 2ft High Capacity Ceiling Box with 4U Drop Down Rack and Smart Power Module


The FSR Inc CB-224 series is a 2’ x 2’ high capacity ceiling box designed to fit into a standard 2’ x 2’ or 2’ x 4’ drop ceiling. It features a drop-down 4RU cage for easy installation and mounting of rack equipment. Cable guides for service loops are provided to allow the equipment to be connected in the down position and then slid up into place. The drop-down cage features pneumatic assistance to counter some of the weight of the equipment installed.

The CB-224 has 5 AC outlets in the box and 1 in the room. A master power switch is accessible from the room.

The ‘P’ option adds an adapter for projector pole mounting. This allows cabling to pass from inside the ceiling box, down the pole and to the projector, providing a nice clean installation.

The ‘S’ option adds cooling fans and the Smart Power module. This module allows the power in the box to be either remotely controlled or switched based on the current draw of specific outlets. In this energy saving mode, the power in the box is switched on and off automatically with the projector to conserve power.

The CB-224RKRL optional rack rail hardware kit adds two additional rack spaces at the rear of the CB-224 cage for cable management and mounting of accessories.

There are a variety of accessory internal mounting brackets available including one gang, two gang, six IPS and twelve IPS openings. They can be positioned and mounted as needed using various pilot holes located at the top of the cage.

The CB-224S is the non-pole mount model with the smart power module and measures 2 ft x 2 ft.
