Ring Failure

Blinky,

for the record:

DMM's production and assembly is in-house in Llanberris in North Wales. Been there and seen it, very impressive set-up with a dedicated, highly motivated work force and management.

Regards,

Mark.

Some of us old schoolers still use drop forged steel for all our primary support locking connections exclusively.

Very interesting....most harnesses these days dont have steel D-Rings, maybe Sierra Moreno and Weaver are the only ones left? Are there any obvious disadvantages of using steel connectors for climbing other than the small issue of weight?......can you give an example of these connectors? are you taking about using 3 way twist locking steel rigging biners for climbing or locking steel snaps?

Use of leather cambium savers is a good way of avoiding rings and stuck climbing lines altogether!

Leather cambium savers have their place, its just that that place is 1973.

I use the locking steel snaps myself. I never use any kinda biner for lifeline attachments, like Scott Prophett did.

Funny, 1973 is when I first began climbing trees commercially!

I know, I'm an old school dinosaur. But I'm still alive and climbing!

Apparently locking shackles aren't needed. The ones pictured are the standard issue ones that come stock on the saddle when you buy the tree flex. They do have some rubber/plastic washer inside that provides some sort of vibration protection or something like that.

I thought about putting shackles down below, as well. I prefer not use them whenever possible.

I like Mark's idea. You could use the snagless bow shackles like on the BFII. I locked mine with Permatex and they didn't budge until a couple of weeks ago when I took the old rings off. The Permatex was a good idea, the bolt came out slowly requiring a wrench the whole way.

If you girth hitch the ring you defeat the value of a bridge since the ring won't slide... or did you mean something different?

It's too bad you have to take this into your own hands without guidance from the manufacturer. At this point I have no confidence in Tree Mettle Nexus.

Nope...something different. I'm splicing some footlock prusiks right now. When I'm done, I'll splice up what I mean and install it on the harness so you can see.
