DMM made the V-Twin Belay Device out of stainless steel instead of aluminum to increase durability and keep it cooler on long rappels. The deep V-shaped grooves provide solid breaking performance on ropes ranging from 8 to 10.5mm, so you can take it along whether you're using your fatty on a sport route or bringing twins on an ice line. You may expect the V-Twin Belay Device to be heavy, but thanks to DMM's investment casting manufacturing process and close tolerances, it weights a mere 3.1oz.

Bottom Line: The DMM V-Twin Belay Device lasts longer and stays cooler.

Talk shop with all the gear freaks out there: ask 'em questions, upload/browse photos, and give your 2¢.

Tough on the Carabiner

By:

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.
