The Web Retractable Lifeline is designed with an ergonomic frame to make handling more comfortable for the user. It is also supremely lightweight and features a durable aluminum housing. With its quick-action braking system, this lifeline offers ultra-dependable performance, and it also meets or exceeds all applicable OSHA and ANSI regulations. Unlike other self-retracting lifelines, no recertification is needed with the 6 Web Retractable, since it is considered to be a disposable unit.
