The RGA1 is a retractable mini block ideal for personal issue for operatives working at height. The unit is designed to be connected and worn in conjunction with a fall arrest harness. The RGA1 has an almost instant lock-off in the event of a fall, and recoils into the drum when slack is introduced into the lanyard. The reduced trip hazard and compact design make this unit ideal for confined work. The addition of a swivel hook avoids twists to the webbing.
