Call me old fashioned but these nuts are the best
Call me old fashioned but these nuts are the best. BD nuts are the mainstay stopper in a climber's rack. There are very few constriction cracks where these don't work. Although they are not "off-set", they have a trapezoidal shape that allows them to be on placed their horizontal securely in mildly off-set cracks.

Buy it already!
A great value and solid protection for a small amount of real estate.
Mandatory Part of Your Trad Rack (and Your Friends' Too)
BD and, before BD, Chouinard, has made what i think are the best stoppers since, well, since good stoppers have been made. Get a full set and you'll be the envy of your Trad partners. Talk 2 of them into buying the same full set and you'll be ready to climb the Tower together ;-)

Stoppers
I have used Stoppers since the first version in 1972. They place consistently, clean easily, and do the job they are designed to.

Best nuts around
I've been using BD nuts all my life and love them to bits. They are simple, reliable and affordable and they work in every sized crack you can imagine.
