Petzl GriGri+ Belay Device

The Petzl GriGri+ takes the familiar GriGri design and adds an anti-panic handle and a mode selector for top-rope or lead belaying. It handles single ropes from 8.5 to 11 mm and is a popular choice for gyms, teaching, and climbers who want extra margin when lowering.

What the plus adds

The anti-panic feature is the headline. If a belayer yanks the handle all the way open while lowering, the GriGri+ locks and stops the descent instead of letting the climber drop. Ease the handle back and lowering resumes. That catches one of the most common belay mistakes, especially with newer belayers.

The mode selector lets you set the device for top-rope or lead. In top-rope mode it engages more readily; in lead mode it pays out rope smoothly for clipping. A steel wear plate in the rope channel extends service life on gym ropes that see heavy use.

The GriGri+ is a little heavier than the standard GriGri because of the extra features. For most climbers, especially in gyms, the extra margin is worth the small weight difference.

GriGri climbing basics

Whichever version you use, the rule is the same: the brake hand never leaves the rope. The cam is a backup. Load the rope following the diagram on the device, test it with a sharp tug before every climb, and keep the handle under control on the lower.

Compare it with the standard Petzl GriGri if you want a lighter, simpler device and are confident in your lowering technique.

Lowering is where most belay accidents happen. Feed the rope smoothly and keep the climber's descent slow and steady. The anti-panic handle is a backup, not a substitute for good technique.

Teach new belayers on the ground, with an experienced belayer as a backup on the brake strand.

For tree workers

Most arborist climbing lines are 11 to 13 mm, outside the GriGri+ range, and tree climbing systems normally use purpose-built MRS or SRS devices. If you are considering it for any tree-work use, confirm compatibility with the rope and with Petzl's instructions first.

The GriGri is designed and certified as a belay device for rock and gym climbing. If you plan to use it in a tree-work system, make sure the configuration is covered by Petzl's instructions, that it meets ANSI Z133 requirements for life support, and that you are trained in it. Inspect it before every use.

Most tree crews will be better served by purpose-built devices for MRS and SRS, which are designed around arborist rope diameters and the way tree climbers move. The GriGri+ is a better fit for rock climbing and gym use.

Care

Keep the device clean and dry, check the cam and anti-panic function before each session, and retire it if the rope channel shows deep wear or any part is cracked or bent. Record inspections for shared crew or gym gear.

Store it dry and away from chemicals that can damage the plastic. If the device has been dropped from height or caught a severe fall, inspect it carefully before using it again.
