The Cable Chase is designed to provide a straight, clean path for wires with no obstructions. The brackets allow you to greatly reduce friction and stress on wires being pulled through the holes due to the hole design. Using the Cable Chase instead of drilling holes will greatly reduce the damage to floor joists, LVL's and manufactured wood. It will also provide less opportunity for the wire to become damaged because of crookedly drilled holes, sharp wooden edges or wooden splinters. The easiest and safest way to route wire and cable. Reduces labor, equipment and is expandable upon in the future.
