Petzl Grigri Belay Device

    Belay device with assisted braking, compatible with a broad range of single rope diameters, for both gym and crag:
    - feeding slack and catching falls are done using standard belay techniques; always keep a hand on the brake side of the rope
    - belaying convenience, thanks to assisted braking: when a climber falls, the device pivots on the carabiner, the rope tightens and the cam pinches and brakes the rope. Holding the brake side     
of the rope helps engage the cam; therefore, it is important to always hold the brake side of the rope
    - compatible with dynamic single ropes 8.5 to 11 mm, optimized for 8.9 to 10.5 mm
    - rope installation diagram engraved on both the interior and exterior of the device
    Exceptional convenience when lowering:
    - the ergonomic handle allows you to easily unblock the rope and lower someone
    - easily controlled, progressive rope feed provides a smooth and comfortable descent
    Intended for all users:
    - simple to use for belaying both lead or top-rope climbers
    - optimally balanced design: lightweight (175 g), compact and durable
