Construction sites and municipal services are generally considered harsh environments and that’s where the CFL-6-Z7/9FT Black Rhino™ SRL with steel locking rebar hook from Miller outperforms its competitors. This 3/16” stainless steel self-retracting line withdraws smoothly into a housing made from aluminum, stainless steel and impact resistant thermoplastic. At 9’ the line grants the user a wide radius to work in when unraveled at a gentle rate but if a jolt is experienced the fall limiter will engage in split seconds ensuring the line locks in place to arrest the fall. The system is rated at 310 lbs working load while the 2-1/2” gate locking rebar hook harness connector as well as the 1” gate twist lock carabiner have a massive 3 600 lbs tensile strength ensuring they never reach their breaking point under normal working conditions. A handy visual load indicator makes it clear to the user if the line needs to be serviced.
