A strain relief bracket for use in conventional and modular furniture applications guards against excessive bending of copper and fiber optic cable. The device is a substantially rigid durable bracket that has an adhesive surface for adhesion to the interior of a furniture wall. The device is bi-planar, having a first section in a first plane, a raised flange section in a second plane, and a second section connecting the first section and raised flange section. A flange at the end of the first section secures the bracket to the edge of an opening in the furniture wall. Cables are secured to the bracket by cable ties that extend through holes provided on the raised flange section. The bi-planar arrangement of the bracket minimizes the bend radius of the cables and thereby strain relieves the cable, adapters, and connectors in the wall.
