Two things suck about strapping things down, either your stuff is too loose so it wobbles around, scratches, dents and possibly falls off en route, or the webbing is pulled taut enough to play a high ‘C’, resulting in an uncontrollable and unpredictable release of tension to free your belongings from absolute bondage. These straps feature a unique die-cast zinc alloy housing and stainless steel torsion spring design for easy load adjustment and controlled release than more conventional cam-lock devices. Easy, secure, safe. Heavy duty, high strength 1" wide waterproof polypropylene webbing can be configured into multiple configurations for tie-down versatility. Working load limit is 700 lbs, with a break strength of 2100 lbs. Available in 3 sizes - 6', 12' and 18'.
