Everyones favorite accessory carabiner the XSRE is now available with the option of a locking screwgate and captive bar for extra security. The removable threaded captive bar helps ensure the correct orientation with lanyards and holds components securely. Made with the same attention to detail as all our standard size DMM carabiners, the XSRE Lock CB is a perfectly formed, high performance accessory clip. It has a functional industrial pedigree, yet crosses over easily into everyday life situations. Widely adopted for non-PPE use on working at height sites, the XSRE is just as useful on a tree care harness to organize gear as it is for clipping keys onto a belt loop.
