WM2 - Our best seller! Ideal for operations where cords must be moved often, or have to be kept neatly out of harm's way. The WM2 is a clean design, modern in appearance, easy to install and use on a daily basis. Secures to the back or sides of desk or work surface with optional double-sided tape or staples. Easy to use, too. Just open the top of the "J" a bit and slip wires inside.
