Bought for PFD, climbing

Familiarity:
I've used it once or twice and have initial impressions

I have some other DMM stuff and like their quality. This piece looks useful in force multiplier situations like rescues. Nice to have around.

Depends on rope

Familiarity:
I've used it several times

Purchased these to add to a crevasse rescue kit, but unfortunately you can't get 8mm rope to consistently track on the roller. The odd shape of the top of the caribiner and narrow opening at the bottom mean it's not very multipurprose at all either.

Awesome, but EXPENSIVE

Familiarity:
I've used it several times

Ive always been an atc guy, and the rope always had some serious friction when lowering. This twist on the classic carabiner is an awesome addition. My partners daughter has recently started climbing with us and she weighs 50bs soaking wet, so when lowering her I was finding myself forcing the rope through my atc. With this as my belay biner I have much more control while lowering her. But this one carabiner is as much as a cam, so overall I do like it alot but it depends on where your prioritys lie.

Nice Product, Extraordinary When Needed

Familiarity:
I've used it once or twice and have initial impressions

The DMM Revolver Locksafe Carabiner is a gem of workmanship and ingenuity. The Revolver is capable of various tasks including line haul pulley and friction management for ease of rope movement. Did Not put through any practical applications as of yet but, set it up to try it on a light line haul load. The Revolver keeps the rope moving smoothly with no friction wear. Plenty of strength for most applications and easily integrated with climbing harness, anchor point and friction management during descent. A supplemental pulley in a carabiner package.

Keep them in my PFD pocket

Great for a basic wrap kit.

Great

I carry 2 in my PFD

Familiarity:
I've used it once or twice and have initial impressions

I carry 2 of the screw lock revolvers in my PFD pocket. Along with a couple of 5mm prusiks and my throw rope I have a very basic wrap kit on my person while on the river.

Great for what it is supposed to do

Familiarity:
I've put it through the wringer

This is very much a niche product. You can't really belay with it or use it as a dedicated pulley. It fits somewhere in the middle, acting as a sliding biner along you system. I have found two places where it really excels: on a chest harness and on a traveling anchor. Putting this on a climber's chest harness really helps to reduce drag when rappelling. I also like using it on traveling anchors at the top of multi-route walls because I don't have to stop every few steps to pull on it and it will catch me if I fall. Great product, just don't expect it to replace your existing biners or pulleys.

Great for Swiftwater Rescue Applications

Familiarity:
I've put it through the wringer

When used for tether Zip Line / Tension Diagonals across swiftwater missions, the built in pulley reduces friction allowing faster line times, therefor increasing safety of rescuers by reducing the amount of time in debris filled. moving water. Model with larger Gate opening would be nice

Great binder but expen$ive

Familiarity:
I've used it several times

I bought a couple of locking revolvers for a trip to the gunks where there are a lot of traversing routes and overhangs. These worked out perfectly. Strung together three pitches and literally no rope drag after 200 ft of couple 30 foot traverses, roofs, etc. Gray Dick said use double ropes. This was a less expensive and lighter way to to deal with rope drag. I bought mine on sale for $25. I really like them but not for $50. I think it will help next time I do cat in the hat at red rocks when you run the traverse and the last pitch together.

9.8 Rope + Carabiner

Great Carabiner

You know, this picture says it all. Great picture. It just made me want to buy this carabiner..

waste of money

This carabiner does not work with the tibloc for a rope grab as well as this pulley is not as efficient as some other pullies you can get for around the same price range, for instance the rock exotica pulley. Overall, the idea was good but the product is overpriced and inefficient.

This product is not meant to be a pulley. It is a Caribiner that puts about 30% less friction on the rope.

great design

If you have ever tried to pull a large person out of a crevasse, you may have encountered some serious resistance, this pulley applied at the right spot could save you lots of effort. The reduced friction is key and I love this biner. Essential piece of equipment in a crevasse rescue kit.

Good for a haul pulley

I use this as a haul pulley in a Z-Rig for light & fast mountain climbing. When it's just me and a bud, they're fast & quick. Funky shape makes kind of useless as a replacement in all situations.

Does this site have the screw gate version of this ?

Backcountry does carry it, but it's not in stock right now.

Has anyone tried this for canyoneering?...

Has anyone tried this for canyoneering? Do the pulleys still work when they get sandy?

these aren't really made to be used as a full function pulley, mostly to reduce rope drag and as a last resort. and i have personal experience with this 'biner from a friend and after a couple gusts of sand at lake Powell the pulley on it wasn't much more useful than a large round HMS 'biner. that was just my bad experience with this and I'm sure many people have had good ones but the desert really isn't where they excelled for me

To awnser your question the carabiner's "pulley" would work in semi sandy conditions and possibly even very sandy conditions but if i were you i would stick with just getting a pulley because from what i have heard the "pulley" is too small and doesnt have enough surface area to be very efficient. I hope this helped.

Idle curiosity forces me to question whether...

Idle curiosity forces me to question whether or not that axle on that pulley can hold up to the full 24kN the biner is rated for and still roll smoothly afterwards. The manufacturer's website definitely implies that they are meant to take a fall, but doesn't state how well it will continue to roll. Thoughts/experiences?

Good question, most likely they addressed this when developing and testing this, I really don't think it would be up on this site if it did break like that. One thing to consider is how well it integrates into the rest of the biner, there is really not a lot of play for it to break. If it did, backcountry.com would replace it for you anyway. Hope that helps.

This was taken strait off DMM's website "It is also very strong, and the spindle will not deform until a force approaching 10 to 12 kN is generated." It is unlikley that in a climbing fall you would generate more than 10 kN. And if you did than the broken pulley on your biner would be the last thing you would worry about. So feel free to take some falls on it, thats what they made it for.

DMM also mentioned that if you did exceed the maximum limits and it did deform it operates like a regular standard carabiner. I'm not concerned over deformation and the bearing locking up but I would have a problem if the roller completely broke off. Would it shred your rope or can you complete your activity safely.

Can I use this with my squat rack and climbing rope to pull 45lb plates? I have limited gym space and this would be convenient. Would the dry lube bearing hold out on this?

I'm not sure how well the pulley here would hold up, but your bigger problem is going to come from using your dynamic climbing rope to lift weights, most of your range of motion will be expelled into streching the rope. Also, you are putting alot of cycles into your rope. I would suggest using a dedicated pulley: http://www.backcountry.com/outdoorgear/Black-Diamond-Pulley/BLD0112M.html and a length of static rope. I don't know how practical that is for you, but I think you will save yourself a lot of headache in the long run if you don't use your climbing rope for this.

how many of these rings do i need for the tree fort?

I suggest you get a cheap carabiner. If you want a pulley, get one from Lowes or one like this http://www.backcountry.com/outdoorgear/Black-Diamond-Pulley/BLD0112M.html

The images for the 'quicklock' and 'locksafe'...

The images for the 'quicklock' and 'locksafe' locking options are incorrect. DMMs website (http://www.dmmclimbing.com/products.asp?pid=3) states the 'locksafe' gates are colored green and have a 3-step release. The 'quicklocks' are colored red and have a 2-step release. If you look at the pictures themselves you can see (on one side) that the green colored gates have and three stage release and are the actual DMM locksafe gate. However, in the images they are labeled as the quicksafe. So, my question is, if I want the the 3-step release gate (the actual 'locksafe' according to DMM) which one do I order; the one that is labeled locksafe or the one that has a picture of the locksafe. Another way to ask this is, did backcountry mix up the images or did they mix up the names? Thanks for your help.

Try using Chat Now and they will get you an answer since they are in the warehouse. That should help you alot more than us gear heads can.

I chatted with a tech and they guessed the images were mislabeled. I went ahead and ordered one and they were right. If you want the the 3-step release gate that DMM calls 'locksafe' the order the 'locksafe' from the pull-down menu. Ignore the labels on the images (they're wrong as of 12 June 2009) thanks
