Lockstraps are a combination between a lock and tie-down (strap). A resettable carabiner combination lock is combined with a steel cable reinforced 1-3/8" wide strap. The stainless steel security cable runs inside the entire length of the tie down.
Several variations are available. From a 8.5ft tie down with locking carabiners on each end, a short 2ft helmet and gear lock to a 24ft long security strap.
