The Ultra-Lok™ line of SRLs is backed by decades of field testing as one of the most reliable and rugged fall arrest options on the market. The 20 ft (6.1 m) galvanized steel cable resists abrasion in harsh conditions and the swiveling anchorage point prevents tangles, while the internal energy absorber minimizes dangerous arrest forces in the event of a fall. The semi-sealed design features a gasket in the housing seam that keeps out debris, and the swiveling self-locking snap hook can be operated with gloves on.
