Safety Something YOU can live with!

100% tie-off systems that incorporate self retracting lanyards (SRL) with innovative mounting brackets attached to the harness back D-ring are now available. These systems may be an alternative for conventional double lanyard systems often referred to as "double leg", "twin tail", or "Y-lanyards" for 100% tie-off.

100% Tie-Off Fall Protection System Remember these lanyards were designed to allow you to stay protected (100% tie-off) while you move from one location to another (Examples may be transitioning from a man lift to a roof top, climbing vertically or from vertical structural steel to a horizontal structural steel lifeline.). In an alternating or "leap-frog" fashion the user attaches one SRL to an anchorage point, moves to a new location, attaches the second SRL, then disconnects the first SRL and moves again. An advantage of using double SRLs versus conventional double legged shock absorbing lanyards is maintaining a shorter fall distance and eliminating the need for different fall protection equipment to address changes in fall clearance.
