Gardner Bender 14 in. L Black Self-Cutting Cable Tie is a patented design that 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 result. | Gardner Bender | | 14 in.
