The Tracpac F2 extendible rescue lanyard with dual shock absorber is composed of a dual shock absorber to which an extendible lanyard is attached. The dual shock absorber prevents injuries from a lateral pull during a fall. The total length of the lanyard stretches from 4-1/2 to 6-Foot (1.4 to 1.8 m) providing mobility to the worker without the clutter or hindrance of a long lanyard. The stretch within the lanyard arm also acts as an indicator when the user is nearing the maximum length of the lanyard. This eliminates the unpleasant nature of a sudden stop experienced by conventional shock-absorbing lanyards. The extendible rescue lanyard with dual shock absorber also doubles as a rescue line by providing an in-line connection point which allows the victim to be raised or lowered safely after the fall. The rescue ring on the unit allows the rescue team an easy access connection point so that the lanyard, which is under tension of the victim's weight, can be disconnected from the user's anchorage point allowing for a more effective and time efficient rescue. The Tracpac F2 extendible rescue lanyard with dual shock absorber is designed to be used when a risk of fall up to a maximum of 12-Foot (3.6 m) exists and the user weight is less than 310-Pound (140 kg). It can also be used for a 6-Foot (1.8 m) fall arrest for users up to 386-Pound (175 kg).
