The 2U 19 inch sliding server rack mount shelf features a versatile and vented design to ensure it works great for all your computer, AV, network and data equipment needs; perfect for IT and business professional alike. Offering a weight capacity of up to 50lb (22.7 kg), the sliding rack shelf features a ventilated, cold-rolled steel shelf on two locking adjustable rails which allow the shelf to be installed into cabinets or racks with mounting depths from 20in (510mm) to 30in (744mm). The locking feature locks the shelf 3/4 of the way out, preventing the shelf from accidentally falling out of the rack or sliding back in before maintenance is complete - a perfect solution for storing small, non rack mount equipment, tools, peripherals or accessories in your rack or cabinet to keep them readily accessible. As well, the rugged steel construction holds up to even the harshest industrial environments, helping to keep your equipment safe.
