If you have a large audio/video component system, then you know that proper storage is critical - especially if you're rack-mounting your gear. The Sanus CFR2144 is over seven feet tall, yet it can provide rock-solid support for your system. Sturdy casters make it easy to move, and each shelf is backstopped so your components sit securely during repositioning. Quick-release removable side and back panels give you access to your components. Rack-mount or shelve your gear The CFR2144 can accommodate up to 44 rack-mounted components that are 1-3/4" tall. Or you can use the included shelving to store up to 22 larger components. You also get rack face plates, so you can fill in empty gaps between rack-mounted of shelved components for a cleaner look. Easy cable connections Space behind the shelves lets you run connecting cables between your components. And a three-rack panel that can be attached to either the top or the bottom of the rack's rear gives you options for running wires out from the cabinet. Industrial-strength construction The brawny CFR2144 can support up to 1000 lbs. of electronic gear. Welded heavy-gauge steel construction makes it durable and strong, and a locking tempered glass door gives you added security. Drop-down legs provide stable support, and they're adjustable, so you can ensure your gear stays level. Ventilation to keep components cool Integrated vents along the edges and air holes in the back panel keep air circulating. The cabinet also features cooling shelves on both the top and bottom of the rack for improved airflow. In addition, every shelf also has ventilation slots to help keep the temperature down.
