This white 3/4 inch raceway piece serves as a transition where the cables need to run around the outside of a corner (the wall will be to the inside of the corner piece). It allows the installer to connect two longer straight raceway sections at a corner.
Use surface mount cable raceways to protect and tidy up cable runs around the home or office where running through walls is not possible or practical. These raceways are useful for nearly any type of cable from phone, network, USB, VGA, Audio/Video, Speaker and more. Some sample applications would be: office cubicles where walls are not available or the working space can change configuration or in the existing home where one wants to install surround speakers and hide/protect the speaker cables/wires.Specification
