No-tangle design allows the harness to fall into place when donned. Back web loop replaces standard back D-ring, reducing overall weight and electrical conductivity. Ideal for connection to a rescue system, web design reduces electrical conductivity. Leather insulators behind the remaining hardware for reduced conductivity. Metal to metal mating buckles provide fast and safe connections. Parachute torso buckles completes the 5-point adjustment system for a perfect fit. Nylon web construction self extinguishes after an arc flash protecting the harness, enabling it to safely withstand a fall. Arc flash resistant up to 40 cal/cm2 making it ideal for use where high voltage electricity is a concern. A Velcro® cover protects harness labels and holds an i-Safe™ identification tag for recording and storing information on inspections. Delta™ harnesses combine a set of "industry-first" advancements, with popular features making them the workhorse of the industry.
