PETZL GRIGRI Belay Device - Belay Device with Cam-Assisted Blocking for Sport, Trad, and Top-Rope Climbing

PROGRESSIVE DESCENT CONTROL: 3:1 mechanical advantage of the camming mechanism helps smoothly control the rope and reduce lowering efforts regardless of rope diameter..

CAM-ASSISTED BLOCKING: Cam-assisted blocking ensures a comfortable belay—when the climber falls or weights the rope—the cam in the device automatically cinches down to arrest the rope.. COMFORTABLE and CONVENIENT: Simple to use for belaying both lead and top rope climbers. Rope installation diagram engraved on the inside and outside of the device serves as a friendly reminder to novices and experts alike.. TWIST-LOCK: Automatic locking, optimal for connecting lanyards and connecting a GRIGRI to the harness.. LIGHTWEIGHT PERFORMANCE: D-shape is functional regardless of orientation, meeting multiple uses: attachment of a belay system, a pulley, or on the end of a lanyard. Light enough for mountains, durable enough for the crag.
