|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 #1940: Ball Lock and UIAA forged onto the spine, and not on the plastic sleeve. Batch marking is on the spine-left rather than spine-exterior. These differences suggest earlier production than 1940.
