The SRDRAWER4U SmartRack 4U Locking Rack-Mount Storage Drawer is a convenient way to keep tools, cables, notes and essential accessories for your rack-mounted equipment at your fingertips. Constructed using cold-rolled steel with a durable black powder-coated finish, this rack-mount drawer has a maximum load capacity of 50 lbs (22.7 kgs). Recommended for quick storage in your data center, wiring closet, back office or anywhere else you keep rack equipment, the SRDRAWER4U mounts to your EIA-standard 19" 2-post or 4-post rack using the included hardware. It locks securely with the included keys to help prevent damage, tampering or theft. When not in use, the 4U drawer slides smoothly into the rack, out of the way until the next time you need a quick screwdriver or patch cable.
