The StopLink brake assembly is an inline absorber for the SafeWaze Mobile Safelink system and subdued edge work. This brake allows four workers to be tied off at the same time, and with low minimum clearance heights. Safelink, the result of a decade of development, addresses the difficulties of work on the leading surface edges of a building under construction, and other applications where horizontal work and low clearance fall hazards exist.Materials: Aluminum housing, Ultrahigh Molecular Weight webbing, Stainless steel connectors, Tensile Strength – 6,700 lb 3039.07 kg Steel carabiner
