Abstract: A two-piece cable tie is provided that is capable of usage with an automated cable tie installation tool. The two-piece cable tie accommodates improved gripping of large or small bundles. By including a cored-out region near the neck, the cable tie can secure a near zero bundle size. By including a transverse pad on the bottom side of the cable tie strap near the cable tie head, the cable tie can be prevented from rotation relative to the bundle to which is it secured. A preferred cable tie strap has a wide recessed center section and high side rails that increase lateral clamping force. To resist barb inversion, the cable tie preferably includes a reinforcement area underneath the metal locking device when used with a strap having a recessed area. By maintaining relatively high side rails and a thin web section in the tip, the cable tie can achieve zero insertion force while maintaining sufficient strap rigidity and size to enable feeding of the strap through an automated cable tie installation tool.
