These Wire Management Clips are great for sit to stand desks! They conceal your cords and adjust along with your work surface. With a clip on link system, you simply add more links to achieve the desired height and attach them to your desk with either a magnet or tape. The weighted foot at the bottom of the clip link system uses gravity to keep everything in place. This can also be used as a free standing unit without attaching to a surface. Available in black, white, silver or translucent to match your space and blend in to your surroundings. Backed by a 5 Year Manufacturer Warranty!
