Matching high performance with minimum weight, these carabiners are the only aluminum carabiners that meet the NFPA strength requirements for general use. The new key-lock design eliminates snagging when removing the carabiner from your harness. A redesigned gate provides a full 1.1 in. opening on the standard size carabiner. Gate choices include the traditional Screw-Lock, our Auto-Lock that is easy to open with one hand, and our innovative Manual-Lock. Both of the XL carabiners have a removable keeper pin.
