Gardner Bender 45-308UVBSC Nylon Self-Cutting Cable Tie, 8 inch, 50 lb. Tensile, Twist-Off Tail, Zip Tie, 20 Pk., UV Resistant Black

Save time and frustration using the latest innovation from Gardner Bender; the self-cutting cable tie. Easy to use; simply lock and twist to finish the job, with no need for an additional cutting tool! unlike other "twist" ties our patented design doesn't require a reduction in the strength and durability of the cable tie material or multiple rotations to achieve a break in the tie. Instead, a small cutting blade designed into the head of each tie ensures a tight lock and quick, clean cut, improving the appearance of the end result and virtually eliminating residule jagged edges which can bite into bare skin. Ties are made from durable 6/6 nylon and provide 50 pounds of tensile strength.
