Klixon breaker question

Anyone using the Klixon 7277 breakers? If so, are you using the -1 (short) or -2 (long) ones? The -1 breakers look long enough to my eye for standard panel installation.

I've used the 7277 series and see absolutely no need to go to the extended version. My panel is .062 thick and there's plenty of thread to get the nut, lock washer and indexing washer installed. Even the shorter breaker has plenty of length to get your fingers wrapped around them.

Yes and all shorter version. There is plenty of room with my .090 panel.
