As with all the fittings they must be assembled carefully . That crown piece on the hayn, combined with right hand lay wire, can be a real fun time. I wouldn't use those hayns if you are using rh wire, as the strands don't like to stay closed around the cone/crown
.I think stay locks are probably the easiest to assemble because the piece you slide over the wire is the male threads, and the wire ends stick out of it, where as the hayn and norseman have the female threads on the shell over the wire, and the wire ends are down inside of it, a bit harder to work with , especially when the wire strands want to stand against the treads, and not leave room for the fitting to thread together. Can be a pain.

Has hayn changed the slot width on the nut side of their fitting (the cone that goes over the wire) ? I remeber adjustable decent size wrenches not fitting in the slot, but the most recent one I did seemed to have enough room for a wrench to fit ok, so that is no longer a problem I guess ?
