Low profile head is designed to prevent snags on uneven surfaces and easier to pull through bulkheads. Non-magnetic stainless steel locking device insures both maximum strength and the right tightness. Ty-Rap ties provide an infinite number of locking positions and the No-Slip Tail provides easy grip during tensioning. Smooth, notchless body reduces stress concentration points under tension, making the tie stronger and lower profile than notched body ties. Ribbed body grips the bundle and prevents slippage. Rounded edges protect insulation, preventing sharp edges from damaging cables.
