Keeper Cam Buckle Tie-Downsare the perfect alternative to rope, twine and other less efficient methods of securing cargo. The cam buckle is convenient and easy to use and includes a quick-release thumb button, eliminating the need to spend time tying and untying unreliable knots. Cam buckles work in conjunction with compact, vinyl-coated S-Hooks that retain their durability even under the most demanding conditions. With a 300 lbs. working load limit and 900 lb. break strength, Keeper Cam Buckle Tie-Downs are ideal for securing smaller loads.
