FallTech Arc Flash Dorsal D-Ring Extender, 18 in
Provides improved over-the-shoulder reach for ease of connecting lanyards and SRLs. Constructed with Kevlar webbing and overmold insulated D-ring for arc flash hazard protection.
Choke-loop for harness attachment reduces electrical conductivity. Extender use will increase the user's total fall clearance distance when using an energy absorbing lanyard.

Who Needs This Product
A dorsal D-ring extender moves the connection point from between your shoulder blades to over your shoulder, where you can actually reach it. Crews connecting and disconnecting SRLs all day, and workers pairing with tie-back devices, run extenders so hookups are one-handed instead of a two-person job. EdgeCore versions carry leading-edge rated construction.
