| Summary: | plastic sleeve button-lock |
| 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 This is the gold version, which I believe was a color exclusive to Sherrill Tree |
