The BackPack for iMac is a sleek, sturdy steel shelf designed for your iMac or Apple Display. Use it to perch hard drives, USB peripherals or even business cards. Included vertical support pegs allow you to prop up tall drives, Time Capsule or even your MacBook Air. The support pegs are coated with soft silicone so they won't leave any marks on your gear and can be arranged in different formations to accommodate a wide range of devices. BackPack hangs on the back or front of your iMac using two clips and gravity. Built-in cable management rails hold power cords in place for convenience. The shelf can hold up to 3.5 pounds.
