T&B’s Ty-Rap® Cable Ties feature these important advantages: • Stainless steel locking device in the head. Ty-Rap® cable ties are infinitely adjustable within their bundle range. You get the right bundle tightness every time. The 316 stainless steel locking device in the nylon head secures the tie with the longer-lasting, corrosion resistant “grip of steel,™” exceeding the minimum pullout strength requirements specified in MIL-S-23190. • Smooth body design with smooth rounded edges and uniform cross sections. The ties have no notches, thereby reducing stress areas that can weaken the tie and cause brittle breakage especially in cold and dry conditions. Smooth edges won’t snag while pulling through bulkheads. There are no sharp edges to be the source of installation injuries or to damage the wire insulation. The smooth surface design also adds an attractive finish to your wiring project. • Mechanic’s Grip - No-slip tail for easy grasping and tensioning. • Ribbed and stippled inner body – Prevents slipping on the bundle. • Turned-up Tail - Orients tail to head for easy assembly, easier to pick up on flat surface.
