The TY527MX is a 13.4 x 0.27-inch black Cable Tie made of weather-resistant nylon 6.6. 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 every time. Since there are no notches, Ty-Rap tie provides an infinite number of locking positions while fastening the tie at the precise bundle diameter needed. The no-slip tail provides easy grip during tensioning. Ty-Rap tie features an unique friction surface designed to reduce slippage during installation. Smooth, notch less body reduces stress concentration points under tension, making the tie stronger and lower profile than notched body ties. Ribbed and stippled body grips the bundle and prevents slippage. Rounded edges protect insulation, preventing sharp edges from damaging cables.
