CMC ProSeries Aluminum Key-Lock Carabiners
The CMC ProSeries Aluminum Key-Lock Carabiners are highly advanced NFPA General-Use rescue carabiners—patented and engineered for maximum strength with minimal weight.
As the first aluminum carabiners to meet NFPA General-Use strength requirements, they reduce gear weight without compromising safety. The patented key-lock nose prevents snagging, while the redesigned gates provide a wide 1.1" (28 mm) opening on standard models and 2.1" (53 mm) on XL versions. Available in Screw-Lock, Auto-Lock, Manual-Lock, and an ANSI-certified (Z359.12) XL model, all XL versions include a removable keeper pin. Each carabiner is proof loaded and individually serialized for traceability.
