The Tie Boss 3/8-Inch Heavy Duty Rope Tightening System is the upsized cleat-style tightening device — rated for 300 lbs working load and the right pick for ATVs, motorcycles, snowmobiles, and trailer loads where 1/4-inch rope under-rates the job. The 15 ft of included 3/8-inch rope handles most common tie-down lengths.
Wrap the rope around the load, thread through the cam, and pull — tension locks in without slipping back. Releasing is a single-thumb flip. The 3/8-inch rope diameter is comfortable on bare hands even under tension, unlike thinner rope that bites.
Tie Boss is an American manufacturer of rope-based tie-down systems. The full line is made in America with several rope-diameter ratings — 1/4-inch medium duty for tarps and kayaks, 3/8-inch heavy duty for ATVs and motorcycles, and larger industrial sizes.
