DBI-SALA's Nano-Lok offers outstanding safety and versatility in a lightweight, compact package. The 3101236 model of Nano-Lok 6 ft. SRL features an aluminum rebar hook with a large 2-1/4 in. gate opening for easy attachment, and connects to the harness with an aluminum carabiner. When working at height, every extra ounce of safety equipment feels like a ton, but the lightweight aluminum rebar hook makes climbing and safety comfortable. This single-leg SRL weighs less than 3 lbs., so it never interferes with your work. And it costs about the same as a shock-absorbing lanyard, while providing superior fall protection. Nano-Lok self-retracting lanyards are ergonomically-designed and fit easily onto most harnesses. Because the lifeline retracting into the housing, the Nano Loks stay out of the way so you can get your job done. In the event of a fall, the retracting lanyard on this unit locks quickly, generally stopping movement within 24 inches, whereas traditional shock-absorbing lanyards require a full 18 ft. of fall clearance. Nano-Loks provide a 420-lb. capacity, the highest in the industry, giving the user added options for tools and equipment. There are more than 30 configurations to choose from, so no matter what your situation - whether you're working in construction, site maintenance, confined space work, or any other industry that requires fall protection - Nano-Lok has you covered. Nano-Lok SRLs meet or exceed OSHA 1926.502, 1910.66; ANSI Z359-2007 & A10.32 safety standards.
