Ensures a Proper Bend Radius to Reduce Cable Stress and Keep Your Cable Tray Organized This SmartRack® exit clip helps reduce bend-induced stress, pinching, pressure points and fatigue in your wire mesh cable tray system. It mounts to the cross member of the tray to route copper cables down through an opening in the side of the wire mesh. The SRWBWTRFL is 90 millimeters wide and snaps to the wires with no hardware needed. You can also snap adjacent exit clips into the tray to expand the width of your bundled cable drop.
