Twelve South

Mounting Shelf

For iMac and Flat Panel Displays
Little shelf that is out of sight, but not out of reach
BackPack Mounting Shelf is a sleek, sturdy shelf designed exclusively for your iMac or Apple Display. This gorgeous slice of steel makes a perfect perch for hard drives, USB peripherals or business cards. Included vertical support pegs prop up tall drives, Time Capsule or even your MacBook Air. BackPack Mounting Shelf hangs on the back (or front) of your iMac using two clips and gravity. Built-in cable management rails hold your power cords in place for grab-and-go convenience. BackPack Mounting Shelf is here to help you create the minimalist zen-like workspace your Mac was made for.
Hangs on the front or back.
Hang BackPack Mounting Shelf on the back of your Mac for taller peripherals or to dress up your workspace with trophies or Transformers. Attach this cool little shelf to the front of your Apple display and stash your iPhone, wallet and keys or mini hard drive up and off of your desk.
Or imagine this killer setup: a MacBook Air resting on a BackPack Mounting Shelf on the back of your Thunderbolt Display and a MacBook Air SuperDrive parked on a second BackPack Mounting Shelf in front. The choice of what to display and store on your BackPack Mounting Shelf is half the fun of owning one.
VIP parking for gadgets and gear
BackPack Mounting Shelf is the perfect place to park portable hard drives, hubs or other USB peripherals you want to hide, but need easy access to. Built-in cable management rails on each side of BackPack Mounting Shelf keep your cables in place. No more watching your power cable slip to the floor when you unplug. You can even tie the extra length of cable to the BackPack Mounting Shelf rails to keep things super tidy. When you bring your hard drive back to your Mac, your cables are ready and waiting.
Tall is no problem for this small shelf
BackPack Mounting Shelf includes four vertical support pegs that hold vertical hard drives in place. The vertical support pegs can also be used to safely and securely prop up Time Capsule, Airport Extreme, MacBook Air or any other device that weighs up to 3.5 pounds. Coated with soft silicone, the support pegs will not leave any marks on your gear and can be arranged in different formations to accommodate a wide range of devices.
