These are the bread and butter of my rack, most frequently placed gear. Love them because everyone else on the face of the earth climbs with BD stoppers, and so its easy to get my stuff back. Also, they are about the same shape as the BDs so its easy to transition if you ever have to use someone elses rack who uses BDs. Coloring is very easy to spot.
Awesome standard nuts. The difference between these and the BDs are that these are a little narrower, and in my opinion fit better in the shallow cracks out here.
