The 3101218 model of DBI-SALA's Nano-Lok self-retracting lifeline has a steel snap hook at both ends, so you'll have a solid steel connector on both your harness and anchor point. The snap hook has a 3/4 in. gate opening, and provides 3,600 lbs. of gate strength. This is an extremely lightweight SRL less than 3 lbs.! It's also affordable, costing about the same as shock-absorbing lanyards, while providing superior fall protection. There's never been a more reasonably-priced or higher quality SRL on the market. Nano-Loks are versatile, compact, and built with the user in mind. You no longer have to sacrifice comfort for safety. There's a 420 lb. capacity, so you won't have to leave important tools behind. Nano-Loks attach directly to most harnesses and stop falls quicker, usually within 24 in., keeping the force off of the user and making self-rescue possible. Shorter fall clearance is a great benefit to workers, since traditional shock-absorbing lanyards require 18 ft. of clearance before the user is protected. They're also 15% lighter and 30% smaller than the top competitor's SRLs. There's a wide array of configuration options available more than 30 depending on your anchorage type, connecting device, personal preference, or fall arrest needs. This trusted, reliable SRL meets all OSHA and ANSI fall protection standards including ANSI Z359.1 and ANSI A10.32. Length: 6 ft.
