decent biner for 2 | |
| Rating: |  |
| i bought this biner for my two inch slack line hoping that the two inch side was going to be big enough to lay the line flat with out bending putting to many kinks in it. for those of you who dont know what im talking about, slacklining is like tight rope walking, except with tubeler nylon climing webbing. my 2" line needed bigger biners obviously because its a bigger line than the one inch line. imagine the two inch flat line trying to rest flatly on the rounded and of a one inch biner. its gonna bend and if you need that line to be flat to keep proper tension it becomes a problem. now luckily i didnt have this problem too much. it sat flat enough to were the tension would hold. but as for all you other slackliners out there, try and find another "bigger" biner for your two inch line. if you cant and these are the biggest you can find, well [*]give the little guys a chance and let em do there duty and hold some tension. high tension rating as well, good product black diamond. | |

Fantastic Low-Cost Locker! | |
| Rating: |  |
| Great biner. No question. These huge, low-cost, beefy, colorful, easy to clip, locking, biners are simply fantastic. The keylock is superb! Never again will you be stuck fighting to get the webbing out of your biner or your biner out of a bolt. Simply put, I can't buy standard gate biners anymore. I love the colors and the gates are really easy to use regardless of ice, snow, or mud. These carabiners are so good that I'm hard pressed to say anything bad about these biners. But... they do crossload easily (especially on a drop/diaper harness), they scratch really easily and lose their pretty color after little use (a good sign of wear though...), and they are a bit heavy (but then again they are HUGE). These are great for belaying, rappelling, storing gear on your rack, setting up pulley systems/anchors/etc, and generally using them anywhere you need a big, safe, and secure biner. You can't beat them for the price! | |

THE locker for your belay loop | |
| Rating: | |
| Choose this or the auto-locking twistlock version to slap on your harness, or any place you need a monster for rope handling. Because it is constantly round (no weight-saving flat / cut sides), you can run rope over it cleanly, which is exactly what you need for a munter hitch. It's very easy (for a locker) to clip in, and the gate action is wonderful. Some other climbers I've been around don't like that the pin rivet for the gate isn't perfectly flush, but it won't snag either. | |

Great biner | |
| Rating: | |
| I use this biner for my belay device, and it works great. The gate opens wide, and the keylock nose does not snag on anything. It is a pretty big biner, so I wouldn't use it aa an anchor biner or anything like that, but it works great for a belay device. The locking sleeve turns nicely, and has larger threads than Petzl biners, which I like because the sleeve won't spin when you put your thumb on it to open the biner. | |

BD Rocklock Screwgate - Great Size | |
| Rating: | |
| A good quality biner that could use a few tweaks. The size is great and so is the keylock feature - it clips into and out of your harness easily every time. The only downfall is the shape of the biner - it tends to work it's way into being loaded across the gate if you don't keep an eye on it constantly. Just keep an eye on it while belaying and you'll be fine. Rappelling is smooth and easy. | |

Beefy | |
| Rating: | |
| Like the other reviewers, I've also noticed that this biner can cross load sometimes if its loaded and unloaded a lot, because its not quite as D-shaped as some others. Used properly though its rock solid and rope runs over it super smoothly since its super thick, rounded, and has a huge gate. Its my favorite belay biner. | |

Great all-around biner | |
| Rating: | |
| great pear shape, large size, makes this a great all-around carabiner. I use it all the time with an ATC style belay device. I think the diameter is a little too large for use with a gri-gri, but it is great for everything else! | |

Great All-Around Biner | |
| Rating: | |
| A cost-effective large biner for all-around use. When I setup outdoor toprope, I clip two of them around my masterpoint and run the dynamic rope through them. The HMS-style biner is also large enough to easily setup a Munter hitch. | |

Best Value | |
| Rating: | |
| Large gate opening, smooth, snag-free nose. Bigger than it might appear, its perfect for handling multiple lines as a top rop master point. No need to spend any more than 10 bucks on a great locker. | |

Great price for a great belay locker | |
| Rating: | |
| This is great belay biner, it's big, has a large gate opening, round stock, keylock, and it's less expensive than some of the smaller HMS locking biners! It is my favorite belay locker. | |

bad belay biner | |
| Rating: |  |
| I'd say to use it as a carabiner for anchors if you already have it, but it'd be so much better to use an attache anyways. I have talked with others, and in my own experience as well, this thing crossloads OFTEN. | |

Good for the price | |
| Rating: |  |
| For the price this is a great biner. The screw gate is quick and easy to open, but stays locked well. It is prone to dirt in the threds so I try to lock mine down and often as possible which helps. If you're not going to be climbing a ton, or you're on a tight budget I highly reccomend this clip. | |

Quick and easy | |
| Rating: | |
| This is a great all around 'biner. The key-lock is really what makes it worthwhile. Great value for the low price. My only complaint is that putting your colored tape on it doesn't allow a GriGri to freely slide down the spine. | |
