Wire management system consists of a 35” long aluminum track and 15 L-shaped plastic brackets that lock into one another. It is usually mounted in a horizontal plane under or in back of a work surface. End caps screwed into work surface also serve as mounting brackets for the unit. Brackets are large enough and heavy-duty enough to hold multiple cables and wires. And wiring can enter and exit at any point, making this system quite flexible. A big advantage to WM27 is the track can be cut to any length, so if you need shorter just chop to length. If you need longer, use two (or more) and cut as required. By using two or more you can also configure to go around corners.
