The V-SHOCK 3m PFL automatically extends and retracts, allowing the User to move freely around the working area, and includes a selflocking function allowing the User to be arrested quickly and safely in the case of a fall. The V-SHOCK 3m PFL is intended to be used where User mobility is required and fall protection is needed (inspection work, general construction & maintenance worketc.). In certain circumstances (i.e. where the working area has been designed such that the length of the PFL will not extend beyond the edges), PFL’s can also be used for fall restraint applications.
