Black Diamond HotWire Carabiner Features.

Black Diamond HotWire Carabiner.
The world's first wiregate carabiner for climbers, the Black Diamond HotWire Carabiner just got better. This item started the wiregate revolution. It is one of the most popular because it reduces gate shutter, which is the effect of the gate partially opening during a fall. It has been revamped with an updated 20% lighter hot-forged design, yet it maintains the same easy-to-use size of the original HotWire. Its optimal size-to-weight ratio and flat gate-to-rope interface accommodate your finger and can work very well with gloves. The nose angle that is opened slightly improves the ease of clipping. In addition, this offers impressive strength when bending rather than breaking to absorb cross-loading. It has resistance to freezing up in alpine conditions, ensuring its continued popularity even on wet or icy ropes. The large rope-bearing surface helps you build anchors and manage multiple lines with no difficulty. This remains a solid, most robust and popular carabiner available at a good price.

Black Diamond Hotwire Carabiner Reviews:

Positive Reviews:

This is the new & improved version of the Hotwire carabiner which I squandered a year of my life designing at Black Diamond. The idea of a wire gate had been around for quite a while in the sailing world, but the original Hotwire was the first time it was used in a full-strength climbing carabiner and it was initially met with a lot of skepticism. Jonny Woodward was really the product champion of the idea and worked to perfect the concept to the point where it had the same (or better) gate action as a regular carabiner and was as strong. Because the spring steel in the gate is so hard, the crux was figuring out how to peen the ends of the wires.
For rock climbing, my rack is about 80% wiregates and most of those are Hotwires as they are a good all around biner. There are lighter carabiners out there, but the Hotwire is still "full sized" so it isn't fumbly. Wire gate carabiners are much less prone to gate whiplash, which is one of the leading causes of open gate biner failure.
The new Hotwire (shown on this page) is a hot forged version which makes for a lighter biner with the same strength as the old one. Wire gated biners are especially useful for Alpine racks as they are lightweight and not as prone to jamming with snow.

Love these wiregates. They're nice and big, but still pretty light, so perfect for sport draws. The wiregate action is super smooth and has a nice big gate opening for easy clipping. They also just feel good in your hand. In terms of climbing gear, I think this is most important, cause no company sells any gear that's any less safe when used properly, so for me, the biggest factor is the feel and comfort level I have with equipment. These 'biners feel good. Get some. They're great.
I'll also add, for deciding between these (or the HoodWires) and something like the Oz for a sport climbing rack, go with the full-size 'biner. They'll hold up better for longer on hard sport climbs where the weight savings of the Oz won't really make a difference.

The newest version of the Hotwire looks and feels relatively large, but is actually quite lightweight for a full-size carabiner - I weighed one of mine on a digital scale and it came in at 36.5 grams. Simple, "industrial" in appearance, but very functional. The gate tension is on the heavy side which is good for safety/confidence but could make it slightly harder to clip for un-herculean users. The gate has no side-to-side slop when open, unlike many other brands that I own, indicating tight manufacturing tolerances. Because I'm odd, I worked the gate on one of my Hotwires over 1,000 times and it is still nice and "snappy". A great upgrade to this classic carabiner. Parts from USA, constructed in China.

I recently got these in a posiwire quickpack and they've quickly become a favorite rope-end biner.
They are slightly larger than the BD positron biners, with less weight to them AND a much snappier gate action, even compared to most wire gates. This means huge gate openings for your rope end and a nice secure feeling when taking whips.
Anodization on these things peels away pretty fast, but they're not there to look pretty. Construction is great, they're thick for good durability, and they feel wonderful in hand. Always a nice smooth clip with these babies.

Brent Allen at on 12/05/2011

This is the new and improved Hotwire. BD has done it again. The new Hotwire is a few grams lighter then the older model. They are able to cut the weight by hot forging them which allows them to cut weight. They are made right her in the USA in Salt Lake City, Utah.

Overall favorite non-locking carabiner

Only 1oz heavier than the Neutrino with the handling and clipping benefits of a full size karab. I have these on the rope end of all of my quickdraws. I find the flat surface of the wire gate to be super easy to clip even with wet or icy ropes.
jalexander at REI on 04/04/2011

Great biner. I've used this for pretty much all my carabiner needs...I like it because it's a little bit bigger than most non-locking biners and so the gate clearance is better. It's a little heavier than some, but not by much.

Sterling Watson at on 06/01/2012

Just ordered a few more of these puppies. Awesome lightweight wiregate. You can definitely feel the difference between these and the old hotwires. The snappy gate action is a glorious sound to hear after making that desperate clip

Benji R. at on 04/15/2010

Most of my rack is made up of these and I love them! They are light weight and have smooth clipping action. I perfer the use of wire gates over straight or bent.

Jeff at on 05/14/2010

It's so light and useful to clip things onto your pack. I wanted a multipurpose 'biner that was lightweight and this fit the bill perfectly.

Negative Reviews:

I love the shape of the old and new hotwires, too bad the new ones are made with a softer aluminum. I climbed regularly with the original hotwires for five years after replacing them with the new ones which are now half as worn in one year. My rope gets black much faster than ever before . Now I'm looking for wire gate DMM's, they have a much better reputation for not compromising on quality.
