Petzl Grigri Descender
The Petzl Grigri is one of the most recognized descenders in the world — and for good reason. Its assisted-braking cam mechanism automatically locks the rope under a sudden load, providing an extra layer of security during rappelling and lowering operations. For arborists who want the confidence of a self-braking device without sacrificing smooth, controlled descent, the Grigri is the gold standard.
Petzl's engineering delivers a device that's intuitive to use, durable enough for professional daily use, and trusted by climbers and arborists worldwide. Whether you're descending from a work position or lowering a load, the Grigri gives you control and peace of mind.

Frequently Asked Questions
Is the Grigri a belay device or a descender?
The Grigri functions as both — it can be used for rappelling/descending and as an assisted-braking belay device. Its cam mechanism makes it particularly well-suited for situations where hands-free braking is an advantage.
What rope diameters are compatible?
The Grigri is compatible with ropes from 8.5 mm to 11 mm in diameter. Using a rope outside this range is not recommended and may affect braking performance.
Looking for a simpler descender without assisted braking?
See the Classic Figure 8 Descender or the Rescue Figure 8 Descender for traditional rope control options.
Is there a more advanced Petzl descender?
Yes — see the Petzl Rig Descender for Petzl's top-of-the-line assisted-braking descender designed for rescue and industrial use.
