The ProSeries XL Aluminum Key-Lock Carabiners are NFPA General Use-rated rescue carabiners designed for demanding technical rescue, rope access, and industrial applications. As part of CMC's highly advanced ProSeries line, these lightweight aluminum carabiners provide exceptional strength while reducing overall gear weight without compromising safety.

The patented key-lock nose design eliminates snagging during clipping and unclipping, while the oversized XL frame features a full 2.1-inch (53 mm) gate opening for fast, secure connections to ladders, anchors, and large attachment points. Available in both Screw-Lock and Auto-Lock configurations, each XL carabiner includes a removable stainless-steel keeper pin for improved orientation and attachment management. Every carabiner is proof loaded and individually serialized for quality assurance and traceability.
