Rescuers
 working in the most demanding circumstances will appreciate our 
ProSeries Aluminum Carabiners, the first aluminum carabiners to meet 
NFPA strength requirements for general use. Combining high performance 
with minimum weight, these carabiners significantly reduce the weight of
 a rescuer’s gear while maintaining the highest possible margin of 
safety. The patented key-lock design eliminates snagging when removing 
the carabiner from your harness, and a redesigned gate provides a full 
1.1 inch (28 mm) opening on the standard size version and a 2.1 inch (53
 mm) opening on the XL version. Gate choices include the traditional 
Screw-Lock, our easy-to-open-with-one-hand Auto-Lock and our innovative 
Manual-Lock. Both of the XL carabiners have a removable keeper pin.
Every carabiner is proof loaded. Serial numbers on every carabiner.
