Gemtor’s horizontal lifeline system is designed to reduce the force incurred during a fall arrest to a fraction of OSHA-required maximum levels. The specially engineered system is constructed to consider angle of deflection, energy absorption, and friction control to effectively lessen the risk of damage or injury. Unitensioner®, a patented device that automatically limits the tension of the lifeline, makes setup easy. Gemtor, Inc., Matawan, NJ.
