Description & Commentary:

A compact S-Spine belay carabiner that BD designed for use with the ATC belay device. Hot forged, with large rounded surfaces and distinctive large lettering along the trapeziodal spine. Only marked for Major and Open gate strength ratings, the catalog listed (the relatively low) 6kN as the minor axis strength.

This uniform diameter locking sleeve with full-length knurling is shown in the 1996 Spring catalog, whereas the tapered locking sleeve with partial knurling appears in the 1997 Spring catalog - a clear step towards the distinctive locking sleeve BD has used for decades.

This example lacks batch markings, as found on the tapered sleeve versions.

The Airlock had a relatively short production run, and climbers tended to only buy a couple, making it not as common as other 1990's BD carabiners.

The much longer lived Airlock2 carried on the Airlock name for many years.
