Black Diamond Quicksilver Screwgate Carabiner - 2007 BCS

Nothing beats Black Diamond for reliability. These biners are a sure thing.

These are great carabiners, and a great price. But they seem to snag on everything. A keylock nose would be nice, but then it would cost more, and they would call it the Positron.

It gets the job done but is nothing special. The notch in the gate makes getting rope or webbing in and out a pain. This is especialy bad because it is a small carabiner. Also because the caribiner is not rounded it does not work well for setting up top rope. The only upside is that it is cheap. If i was to buy this size locker again i would just pay the extra money to get hte positron locker because is has a notchless nose.

Economical workhorse 'biner that performs in a huge number of situations. Always worth taking a few extra with you, and doesn't empty your wallet to do so.

Great biner for the price. Its a normal size biner. I am a big fan of keylock nose, so next time around i will spend the extra bit to get a locking biner with that feature.

I picked up a few of these guys for a upcoming climbing trip to have a few extra lockers. They came in handy because I ended up having to set up more webbing to drop down into the canyon then I thought. Worth every penny to have a few extra locker because you never know when they may be needed.

Not a bad biner by any means, though there are certainly better options available. Due to the gate notch, I wouldn't use these for rigging anchors or for the bolt end on a draw, but I use a couple for the rope end on locking draws and they work fine for that. Plus, the price is right, so you can afford to get a couple extras to use if you run out of nicer biners. All in all, nothing special, but they work and are cheap.

Great locking biner. Not too big that it takes up room on you rack. But big enough to get the job done. Great classic design that works for many years.

I have several of these and have not had any issues with any of them. They are hard to beat for around 8 bucks. Very durable.

i use these to set up an anchor and they work awesome for that purpose. small and convienent

These are adequate, but are outclassed by many other biners now available. The are light, but the lightness comes at the price of a tinny feel, particularly in the action of the screwgate. Note that they are also not keylock, which makes them prone to snagging on slings at crowded anchors. For a similar price from the same manufacturer, the BD Vaporlock is a better choice, as it is a keylock design and has a slightly stouter feel.

I always try to have at least two or three more of these than I think I will need clipped to one of my gear loops on any kind of climb that I do. I use them for constructing anchors (I try to use only lockers in my anchor systems), for securing my ATC Guide to the master-point on guide mode when belaying a second, and for securing myself to my anchor (also something which it is best to do with lockers). This biner is small, and the nose does catch on webbing and rope as other reviewers have said, but for me this is more than made up for by its lighter weight and cheeper price. This biner is almost as light as a non-locker, which means that carrying these instead of larger lockers lets me carry a couple of extras; important, because one thing that a climber almost always can use more of in an emergency self-rescue scenario (or any unplanned scenario for that matter) is extra locking carabiners.

I think these work great for being a standard locking biner. Great to have for extras, good for anchoring on runners, adequate for belay but maybe a little on the small side.

A twist-gate 'biner is more convenient, but more expensive. This was my first locking 'biner and years later I have many of them. Tough and a good value.

If your looking for speed this is not the carabiner. Good quality just to short of an opening if you were to lock anything bigger than a 10mm rope.

I had originally bought this biner for my primary belay biner. It ended up being too small for that purpose and I switched to the bigger BD Rocklock. I think a collection of these would be good for setting up anchors, top-ropes, and such. I've got a collection of Omega Pacific D-biners which I use for this purpose, so this biner just happens to always be the odd-biner out and rarely gets used.

UPDATE: I've really grown to love this biner and have bought more. I love the price and the weight.

Best priced locking biner around, perfect for tope roping and making bomb proof anchors. The only "minor" setback is the occasional snag when rigging with webbing.

If you must save the 3-4 dollars over the Positron screwgate, then get these. Not anodized like the positron is, so they smell like raw aluminum in your hand (not a big deal). For the price you can't go wrong, but consider something with a keylock nose. I also bought a positron and it is almost identical, except for the anodized finish and the nose (they're pretty much the same weight). Gate action and lock is as smooth as any BD I've used. If you really want to spend the money, go for the super-light vaporlock, but this or the positron will do just fine otherwise.

Simple, strong, effective and cost efficient. More elaborate options exist, they are more expensive.

For the size and price, this is it. It's compact, durable and bomber. I've trusted my life many a time to this superb piece of hardware.

This carabiner is basic, medium sized, strong and less expensive. The screw-gate is basic and smooth. But the metal wears down with continuous use but isn't too bad while other carabiners hold up a little better.

This is a good, lightweight, and inexpensive carabiner. Sure, there are better carabiners, but not for the price range. I have several of these and they have held up really well for anchoring.

Good biner. probably not the one you would want to use for a belay or rappel. Great for setting up anchors and great price seeing as you need a good bit of lockers for setting up some anchors.

Biner is fairly priced and Black Diamond always makes great gear.

When I was just getting into trad I ordered a few of these for multiple uses. They definitely get the job done, although if you want something to use for a MP or use to clip into multiple pieces of webbing/rope you might want to get something bigger. These biners are on the smaller side of things and are not great for things like clipping yourself in. They are still bomber though and useful to have on your harness just in case!

I am in love with Black Diamond stuff. I am not a lable wh*re, they just seem to have some of the leightest and yet sturdy stuff. We are replacing these with auto locking gates, but continue to use them for auto blocks while rapelling. I like them!

Great small locking carab for a daisey chain or setting up an anchor. I wouldn't use this for munter hitches as I prefer something larger like the Rocklock that is more rounded. I keep about four of these on my rack and use them for various tasks -BD makes the best equipment. You can't go wrong with these!

They aren't the largest lockers out there, nor the fanciest, but they perform oh-so-well. Use em for trad and sport racks, and 3 of these go on my alpine set-up because of their versatile size and weight. Never had any problems with the gate or locking screw.

Cheaper than basically any other screwgate out there. I use it for anchors and with my grigri very happily.

solid gear and a good price

These biners are usually pretty cheap - good for anchors.

These are the perfect biners when it comes down to weight, size, and quality. I would definitely suggest using these for setting up topropes, or using them for belaying.

I have a lot of these, as a rappelling instructor, and they are very handy, well built, and can't beat the price.

Great carabiner. Unsrew lock with one finger easily.

I bought both the screw lock and autolocking versions of this biner. I didn't want the auto locker, but my local store only had one screw lock version in stock so I grabbed one of each. I have no regrets.

I spent a Saturday belaying kids who were climbing and rapping. I used the autolocker as my belay biner and the screw lock for anchoring me. The autolocker was great for constantly switching rap lines. Ropes move smoothly through the biner. Price is right, and they are not to heavy either.

These are my choice for basic biners for my belay devices and for my sport route cleaning gear. They aren't the top of the line carabiners, but they are good for basic all around things. Occasionally they will unwind a small amount or get snagged when you're trying unclip them from things they are connected to, but for a basic bottom line, light, faithful biner, this is my go-to option.

After using one of these I had to get two more!! This 'biner is perfect for everything it was intended for; great for top-rope anchors, really good for securing my daisy chain, and only slightly heavier than a non-locking straight gate when extra security is needed on a crux bolt. Really good tools, a must for the all-around climber.

I bought these as a special stocking stuffer for my 10 year old daughter, and I wish that I had purchased a second set (for me) as well!

They are sooo light, and the locking mechanism is smooth and easy to use: now, she is "ripping" up the walls at even greater speed - hopefully, I'll be able to keep up!

For how much the carabiner costs you get alot. It is durable and very lightweight making it a good item to add to your climbing arsenal.

The screwgate has high quality checkering on it giving it great traction. This will be nice if you are using it in icy or wet conditions or if you wear gloves.

Simple, lightweight, affordable and Black Diamond bomb proof- what more could you ask for?

Needed a carabiner to facilitate the building of a single rope bridge and attach to a swiss seat. Tech rep on line indicated this one would work well. Unfortunately, the gate is too small to allow quick connection/disconnection. Other than that the carabiner is light wieght and functions well for anything other than 3 or more 5/8" ropes.

So far I have no complaints. They work great for setting up anchors...not so much for belaying though (a little too small). You can't beat the price for a Black Diamond biner though.

This biner is seriously hefty, in a good way. It feels very sturdy and is made very well. I don't climb myself, but I bought the biner as a connector for a leash for my 65lb Weimaraner. He is a very big, and very powerful dog and I wanted something for thleash I have that is made out of climbing rope, that would not come unhooked. So far it has held very well even in all the angles and twists and pulling of walking a very excited puppy. The price is next to nothing for this biner, so I couldn't pass it up. Good buy, at least from my standpoint.

they are really shinny, you can see yourself while climbing and make sure your bandanna isn't on crazy crooked. great biner for the price you cant bet it.

If you are just looking for a solid cheap locking biner this is a decent choice, I've built numerous anchors with them and they seem durable and reliable. If you have a few extra bucks you could move up to the positron locker and get the sweet keylock nose that doesn't catch on stuff, and if you have a lot of extra money you could move up to the vaporlock and get the sweet keylock and shave some weight at the same time.

Oh, and it's too small to use as a belay biner except in emergencies, so don't buy it for that.

Good solid carabiner here, you get what you pay for with this one.

good for the price!

Black Diamond Quicksilver Screwgate Carabiner. Good carabiner, definitely reliable in every sense. It isn't the nicest, easiest locking carabiner, but it is what you pay for, it works, its reliable and it isn't heavy! Definitely a sure buy.

Light, inexpensive, not too big, not too small. I would have preferred a pear shape, but this works well too. I never seem to have enough lockers when setting complex top rope anchors.

Black Diamond Quicksilver Screwgate Carabiner is a reliable piece of kit. Simple, consistent, what you see is what you get; feels good in the hand, does what it's supposed to as long as you do.

These lockers are great for setting up anchors and the price can't be beat. I got a few of these to try out for the last few weeks and they have done pretty well. I have had a little bit of an issue with them sticking a bit but its not a big deal they still work great! BD gear is always on point and this locker is some good bang for your buck.

screw is so much better then auto. the hook where the gate falls into can be annoying so the higher priced keylock design is nice especially when your rocking a lot of anchors and multi pitch stuff. the size is great, doesn't feel massive.

I like these Black Diamond lockers. They provide the security of a locker but at a low price. I use these for most of my locker needs. The one big downfall to these is the nose sometime catches on slings, gear, etc. If you can spare the extra money seriously consider the Positron or another locker with a keylock nose. I have been happy with my Quicksilver lockers and won't be replacing them anytime soon.

This is a great biner, especially for the price. It is a smaller sized locking biner, and weighs much less than most. However, I don't use it much in anchor systems because of the smaller gate opening. It works well for a personal anchoring biner, or for use with a grigri.

I like these but I would rather go for the Positron if you have the money. They get the job done and keep me safe. Ask for the same color screw on the gate to make it easier in keeping your gear organized.

This locking biner works just the way you think it should. Works great for a variety of purposes when you need to be locked in. The screwgate is smooth and easy to work.

Small, compact locking biner that is strong and durable, excellent for use with a daisy chain.

Most of the biner i have are the colored ones, so when i bought this one i noticed that it smelled a little funny if i held on to it to long, you know, that metal and sweat smell. But if you don't care then it no worries.

Other than that it is a great biner and i will deff buy some more, maybe not the plain metal one : )

BUEN CARABINERO Y MEJOR EL PRECIO, SOY INSTRUCTOR DE BUSQUEDA Y RESCATE
