11/7/2023 0 Comments Gris gris![]() There is a sharp edge on the side that will fray rope if used left-handed, but a smooth flange to protect the rope while belaying right-handed. ![]() This device is not suitable for left-handed belay technique. This device has just one place for installing rope and it can't be used in climbing with half rope. Įach generation of the Grigri has a lower limit for the rope diameter for which the cam will engage the manufacturer recommends the Grigri 2 to be used only with 8.9 to 11 mm diameter ropes. While paying slack out into the system, if the device is held open by pressing on the cam and the climber falls, the device will not lock unless the belayer stops holding it open. When belaying, the same technique for "taking in" that is used with an ATC or similar device is used. When used correctly, the Grigri's camming mechanism can assist in holding a climber that is working a route, or hanging on the rope while trying to figure out a climb. Petzl recommends the device for lead belaying and top-rope belaying, according to EN 15151 standard. Inside the Grigri, the rope runs along a cam the cam allows the rope to pass if moving slowly but rotates when the rope moves more quickly, blocking further movement by pinching the rope against the inside of the device. This function distinguishes it from traditional belay devices such as a Sticht plate or an ATC, whose braking mechanisms depend entirely on the user controlling the rope in a specific manner to increase or decrease friction. ![]() The Grigri works by pinching the rope when it is moving quickly (like in a fall), making it an assisted braking belay device. ![]() It is named for the African amulet gris-gris, believed to protect the wearer from evil. Petzl released the Grigri+ in 2017, adding safety features to the original design, and 2019 saw the release of an updated version of the device, simply called the Grigri. In 2011 a new version, the Grigri 2, was released to replace the original 1991 model. The success of this device has led to grigri becoming a common name for devices of this type. Its main characteristic is a clutch that assists in braking under a shock load. The first-generation Grigri An open first-generation Grigri The Grigri 2, released early 2011Ī Grigri (styled as GriGri or GRIGRI) is an assisted braking belay device manufactured by Petzl designed to help secure rock-climbing, rappelling, and rope-acrobatic activities.
