3M Steel Barb Cable Ties are made from nylon 6/6 and designed with a stainless-steel barb that, when engaged, presses into the strap and grips tight. The strap on 3M Steel Barb Cable Ties features a robust, ribbed pattern to help ensure bundles stay intact, even in high-vibration environments. Unlike typical ratchet-style cable ties, the barb can be locked at any point along the strap, allowing for more precise positioning. The rectangular head design includes rounded corners and a curved tip for easy, fast installation without snagging. These design features are critical when working in extreme conditions.
