Petzl Basic 上升器

The teeth bite into the rope immediately with zero slip, and the ergonomic grip makes long ascents feel almost effortless. It’s simple, sturdy, and gets the job done without any fuss.

The cam mechanism grips the rope instantly with no slipping, even when I'm tired after a long pitch. The ergonomic handle makes it comfortable to hold for extended ascents.

Used this jugging up a fixed line on a windy day and the cam grabbed every time without slipping. The grip stays solid even when my hands are tired mid-pitch, and the release is smooth one-handed.
