Petzl – GRIGRI + – Belay Device with cam-Assisted Blocking

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. Compatible with 8.5 to 11 mm dynamic single ropes.
ANTI-PANIC HANDLE: If the user pulls too hard on the handle, the anti-panic function engages, stopping the climber’s descent. Great for newer belayers and partners with large weight differences.
MULTIPLE BELAY MODES: The lockable selector knob allows you to choose either top rope or lead belay mode. Top rope belay mode makes taking in slack easier and long belay sessions more comfortable.
