|Description & Commentary:|
Introduced in 1997, the Ball lock was Petzl's first triple action auto locking mechanism (predating the Triact), which operates quickly with a button press and 45 degree twist. The plastic sleeve has finger grooves with a molded fingerprint texture. The button protrudes significantly more than the metal sleeved version and I find it more difficult to depress fully.
Petzl's similar manual locking Spinball was introduced later and uses a 120 deg twist.
Differences from : This version lacks the Ball Lock and UIAA #1939 has forged onto the spine. It has them on the plastic sleeve instead. Batch marking is on the spine-exterior (read correctly when the gate faces left) rather than spine-left. These differences suggest later production than 1940.
This is the gold version, which I believe was a color exclusive to Sherrill Tree
