Locking Revolver

[DSMc]

Can the locking revolvers be used to replace the rings on a ring-and-ring friction saver and still comply with safety regulations?

I've used Biners in that application for many years.

There's nothing that I can see that would no comply.

I say go for it!

Works great just be weary of how you remove it. The locking revolver is fairly tight and a washer easily wedges in one and a half hitch will definitely get stuck. Something like the ropeguide bead should work great.

I would say a tandem is good. A single revolver bend radius is 'pretty tite'. I would bet there is significant strength loss due to that.

Not any worse than a carabiner, is it? (keep in mind I've never held a revolver in my hand!)

I'm with Norm on this one, use two. The radius on a single is tight. Plus, the roller is smaller than even and 11mm line. When the climbing line is run through a single revolver at 180 degrees deflection or so, it 'shaves' off a bit of the nap at the transition point between roling surface and non-roling. There is no 'fuzz' when run through two though.

This is interesting information, Tony. Thanks. I have never handled one but I was planning on trying them in a couple of configurations. Doubled as well as single. The narrowness of the bearing sounds like it might be a problem with 13 mm line.

Can anyone verify or refute this? If so, I will find different items to play with.

Thanks everyone. Great input.

Ron did some friction/effeciency tests using a Revolver in a RADS setup. He posted the results on The Tree Climbers Coalition site if anyone is inclined to search for the link.

No problem, Glad the info was helpful. To qualify, I really like my revolvers, but they, like all tools, have limitations.
A single line run through a single revolver at a moderate deflection works great.
(They are too narrow for a double line through a single revolver IMHO) It's when the rope bends greater than approx. 80 or 90 degrees that I have noticed "fuzz".

I am not saying it is weakening the rope, just an observation. I wouldn't want any one to think I got all scientific or sumtin'
