A5 Oval Carabiners
Two A5 Grade VI oval carabiners with 4000 lbs. strength. They seem to be a pretty standard oval design common in the late 1980s and early 1990s. The 1988 A5 Adventures catalog lists SMC “Beta-Biners” for sale but doesn’t show them to be marked with the A5 logo. The Beta-Biners and the A5 Grade VI carabiners are identical as far as I can tell.
