FSR CB-224 High Capacity Ceiling Boxes

The CB-224 is the answer when a 2 ft ceiling box runs out of depth. Its deeper chassis carries a pull-down 4RU rack cage on a gas-spring assisted ball-bearing slide, so a technician lowers the equipment to eye level instead of working overhead through an access door. The cage takes 25 lb, and there is 1 3/8 in of clear space each side of it for wire bundles.

Four versions cover the usual choices: pole mount or not, smart electronics or not. The smart models, CB-224S and CB-224SP, ship with the smart module and fan fitted. Cable entry is edge-protected and foam-sealed on both sides, there are five internal outlets plus one external, and 2RU of angle-adjustable rack surfaces keep patch panel labels visible from below.
