Saw this in the Bartlett catalog. Notice no stopper knots.

The SRT model has a vertical loop in front like most rock climbing harnesses.
Hey J!The stopper knots look like regular sewn eyes to me with a plastic cover. I'm certain it's been tested, but anyone have thoughts on loading the stitching of an eye like that? Seems like it would try to force apart the two legs of rope that are sewn.
Lol.. thanks Levi..If you click on the photo it should go full screen
...the timeline...
..I think the uni is an equal to any newer multiscenders...
I always likened the zig zag to Gorden's OAR or what ever he called it. He experimented with a rope in some roller chain, before he came up with the Bone. The next year the ZZ was born. They are like big bother, always listening....
I don't Hate petzl, it's not like they are KONG or anything.. But they certainly lack in creativity and innovation. They have Meh customer service, and seem to make most of their money selling sport equipment. Hell they just started forging this year instead of selling stamped plate.
I had made a "pulley rack" before the zz was publicly released. I found out later that they had been in development and owned a patent at the same time as I was making the pulley rack, we were unaware of each others design. I still think that they could have a headstock like my pulley rack that would work SRT, and be much cleaner in design.
Hmmm. That’s a decent close up... thanks. So the stopper knot, or whatever is used, will be pressing on the gate the whole time? Wonder what the tensil strength is on that super tiny screw in that black gate.Not sure if this helps. I would think that fisherman knots would work just fine. View attachment 56043
