Self-retracting lifelines offer the unique advantage of extreme mobility coupled with the benefits of a safety line. The CFL-4-Z7/9FT Black Rhino™ SRL with steel twist-lock carabiner from Miller is an expertly made piece of equipment designed to allow the user a 9’ radius from its anchor point if unraveled slowly. If jolted, the quick acting fall limiter brake engages, locking the line in place and immediately stopping a fall. This unit is made to the highest standards with an aluminum, stainless steel and high impact nylon housing surrounding the 3/16” stainless steel line rated at 310 lbs working load. The housing clips to anchor points with a 1” gate twist lock carabiner and connects to most harness and belt systems with a 3/4” gate locking snap hook that features a swivel joint to avoid twisting and tangling. A visual load indicator lets the user know when the line needs to be serviced.
