Description & Commentary:

A metal sleeved version of the Plastic Sleeved v1 Ball Lock, which itself was an autolocking version of the Petzl Spinball. It operates easily with only a button press and 45 degree throw (vs the Spinball's 120 deg throw).

The metal sleeved Petzl Ball Lock suffered from some early issues and was recalled in 2006. It eventually replaced the plastic sleeved version, and is my preferred auto-locking carabiner mechanism for tree climbing if I do not need a steel carabiner or ANSI gate-face rated carabiner. Unlike the plastic sleeved ball lock, the metal sleeved version uses a wider, shallower button, which I find easier to depress. The only downside is that the Ball Lock is only available on the relatively heavy Am'D and William carabiners.

This gold color was exclusive to Sherrill Tree at the time of purchase. I prefer to equip new tree climbers with carabiners of different colors in order to help them distinguish between systems and to help me verbally coach them through an issue.
