Black Diamond
Salt Lake City, since 1989 — the company its own employees bought out of a bankruptcy caused by lawsuits over climbing gear.
Every other brand here sells to people who go up because it's their job. Black Diamond sells to people who go up because they want to. It is the most recognizable name in recreational climbing — Camalots, ATCs, Half Dome helmets, Spot headlamps — and it exists because in 1989 a group of employees bought the wreckage of Yvon Chouinard's climbing company out of a bankruptcy that product-liability lawsuits had caused. Read that sentence again, because it explains most of what the company has been since.

What we'd reach for
- Camalot C4, Z4 and UltralightThe spring-loaded cam that everyone else's cam gets compared to. C4 is the default rack, Z4 handles the flares and shallow placements that used to mean walking away, and Ultralight trades money for grams.
- ATC and ATC-GuideA tube of metal with no moving parts that is still one of the most-used belay devices in the world. The Guide adds auto-blocking for bringing up a second, which is why it lives on so many guides' harnesses.
- Half Dome helmetThe helmet a lot of people buy first and never replace. Tough enough for a gym rack and a crag season, and priced so that wearing one is not a financial decision.
- Momentum and Solution harnessesMomentum is the entry harness that doesn't feel like an entry harness. Solution is the one you wear when you stop noticing your harness.
- Stoppers and HexesPassive protection, essentially unchanged, still working. Nuts don't have a service bulletin problem because nuts don't have moving parts.
- RockLock and the Magnetron gatesLocking carabiners across the range, including magnetic auto-locking gates — genuinely clever, and one of the few real ideas in carabiner closure since the screwgate.
- Spot and Storm headlampsThe headlamp most people mean when they say headlamp. Not the brightest on the market and not trying to be — waterproof, cheap enough to own several, bright enough to walk out in the dark.
- Viper and Hydra ice toolsTechnical ice and mixed tools for people who climb the frozen version.
- 9.2, 9.4 and 9.9 dynamic ropesSingle ropes across the skinny-to-durable range. Worth noting they are a rope Black Diamond sells rather than a rope Black Diamond spins.
On 1 December 1989, a group of employees led by Peter Metcalf bought the assets of Chouinard Equipment out of Chapter 11.
Chouinard Equipment was Yvon Chouinard’s climbing hardware company — the one that started with hand-forged pitons in the late 1950s and went on to invent most of modern clean protection. What killed it was not bad gear. It was product-liability lawsuits, in an era when American courts were deciding what a manufacturer owed someone who fell off a mountain.
So Black Diamond began holding two things at once: a claim to the most important design lineage in American climbing, and direct knowledge of exactly how expensive it is to make equipment that people trust with their lives.
In September 1991 the company moved 45 employees from Ventura, California to Salt Lake City, to be within reach of the Wasatch. It is still there.
Not a work-at-height brand, and that matters
Every other brand on this site is bought by someone whose employer, inspector or insurer has an opinion about it. Black Diamond is bought by someone spending their own money before a Saturday.
That is not a criticism — it is a specification. Black Diamond’s climbing hardware is built and certified for recreational climbing and mountaineering: EN 12275 for connectors, EN 12277 for harnesses, UIAA standards for helmets and rope. It is not built for industrial rope access, it is generally not rated for the descent and work-positioning standards that govern that world, and most of it carries no ANSI Z359 marking at all.
If you are a rope tech reading this page: a Camalot is a beautiful object and it does not belong on your job. Buy Petzl, ISC, CMC or FallTech for that.
If you are a climber reading this page: this is the most complete single-brand rack you can build, and half the gear you already own probably says Black Diamond on it.
The three objects that ended arguments
The Camalot. Spring-loaded camming devices existed before Black Diamond refined them, but the dual-axle C4 became the thing every other cam is measured against. Z4 later solved the shallow, flaring and awkward placements that used to mean downclimbing. Ultralight trades a lot of money for a meaningful number of grams on a long alpine route.
The ATC. A tube of aluminum with no moving parts, no battery, no cam and nothing to fail. It is still one of the most-used belay devices on earth, and the ATC-Guide — which auto-blocks when you are bringing a second up — is on more guides’ harnesses than any assisted-braking device.
The Stopper. Passive protection, functionally unchanged for decades, inherited straight from Chouinard’s clean-climbing revolution. Nuts have no service bulletins because nuts have no mechanism.
There is something worth noticing in that list: two of the three are notable for having fewer parts than the alternative.
Where Black Diamond fits
Rock and gym climbing. Harnesses from Momentum up, Half Dome and Vision helmets, RockLock lockers, HotForge and LiteWire quickdraws, chalk, the ATC. The complete first rack and most of the tenth.
Trad. Camalots, Stoppers, Hexes, alpine draws and Dynex runners — the protection range is the strongest single-brand offering in the category.
Ice and alpine. Viper and Hydra tools, Raven axes, Express screws, crampons, alpine harnesses. The mountaineering side that most climbing brands treat as an afterthought.
Lighting. Spot, Storm, Astro and Cosmo. Not the brightest headlamps sold — deliberately. They are cheap enough to own three of and waterproof enough to survive the one that matters.
Packs. Creek haul bags, Bullet crag packs, alpine packs and rope bags.
Why we rate them
They design for the median climber, not the catalog photo. Momentum, Half Dome and Spot are not the most impressive products Black Diamond makes. They are the ones most people actually own, they are priced so that owning one is not a decision, and they are good. A brand that takes its entry-level range seriously is telling you something.
The lineage is real. Chouinard’s clean-climbing work changed the sport, and Black Diamond is the direct continuation of it. That is a rarer thing than marketing departments would have you believe.
They kept manufacturing at home. Cold-forging and machining in Salt Lake City, alongside a facility in Zhuhai. In a category where almost everyone went fully offshore, keeping a US plant is a choice with a cost attached.
What we’d want you to know
Black Diamond has been owned by Clarus Corporation since 2010, and on 7 May 2026 Clarus told the market its board had begun reviewing strategic alternatives — explicitly including “the sale of all or part of the business,” with Jefferies advising and no deadline set.
Nothing about that changes the gear on a shelf today. But this is a publicly-traded parent looking at options, and it is the sort of thing you are entitled to know when a brand’s continuity is part of why you trust it.
We will update this page when there is something to update.
Black Diamond sits outside all three of the disciplines the rest of this roster serves, which is the point of the section above: rope rescue, rope access, fall protection — three jobs, one pile of gear.
When we reach for a rack, a belay device or a headlamp, we reach for Black Diamond.
