DBI-SALA shock-absorbing lanyards are ideal for reducing snagging or trip fall hazards in energy, transportation, construction and utility industries. In case of a fall, the inner core expands the lanyard up to 6 feet and automatically contract to 4.5 feet to absorb energy and limit the fall arrest forces to safe levels. These lanyards are incorporated with patented self-locking, user-friendly snap hooks specifically designed to open and connect without getting thumb or fingers in the way. They have Kevlar / Nomex construction with zinc plated steel anchor and hooks to withstand maximum weight capacity of 310 or 420 lb. Choose from a wide range of these lanyards, available in single and double leg variants. Raptor Supplies also offers self-retracting lifelinesfor no slack line operation with quicker arrest while falling.
