Designed to be used with the WS-03 Universal Laptop Workstation for C-Stands, the Proaim External Drive Compartment, or EDC, helps to efficiently manage your valuable portable desktop space. Measuring 4 x 2.5 x 6 inches and made from high-grade aluminum, this compartment mounts to the bottom of the Universal Laptop Workstation to securely hold an external storage drive and its cables. Its open tunnel design helps to provide ventilation. Best of all, you don't need tools to install the EDC onto either side of the Universal Laptop Workstation. Instead, you can simply slide it into any of the low-profile slots located on the bottom of the Workstation, even while a laptop is already in place.
