Tough on the Carabiner
By Anonymous
Ranked #456 - Big Wall Climbing

I paired this belay device with a BD Vapor Lock Biner. After about 3 months of weekend use, it had made indents on the biner that appeared to be more than cosmetic. I tried with another type locking biner but got same result. Functions as advertised but the stainless steel seems to damage aluminum carabiners.

This is a stainless STEEL belay device and should be used with a STEEL biner. Pairing this device with an aluminum biner will always result in destroying the aluminum biner - steel is much harder than aluminum. Try using the belay device with a steel biner and that should solve your wear problem.
