The 75-Foot Checkline Temporary HLL Kit can be installed and removed in minutes. The double-braided synthetic rope HLL is rated for four persons over a maximum span of 75-feet. The tensioner is self-adjusting and requires no special tools for installation. This Checkline temporary HLL must be used with a SRL or shock-absorbing lanyard, and can be mounted with two #7372R anchor slings (included) or used with optional stanchions. The kit also includes two #7447 carabiners, four #7401 O-rings, 75-foot rope with integral swivel, one #77700T tensioner and a #5007L storage bag. FallTech vertical lifelines are constructed of premium grade 8200 pound filament and spun polyester over a polyolefin core that provides low elongation and long wear life, abrasion, UV and chemical resistance, and yet stays flexible and renders sure grip and glide through our rope grabs. All of our Rope Grabs, whether manual or self-tracking, allow the user to move freely up and down the vertical lifeline while providing fall protection. These grabs are designed to react to a fall by locking on the lifeline and to begin the deceleration process when attached to one 3-foot shock absorbing lanyard. All FallTech Lifelines, Rope Grabs and Roofer's Kits meet or exceed all applicable OSHA and ANSI standards.
