Ever clipped into a Tricam assuming it’d hold your fall—only to later realize you had no clue what its actual weight rating was? Yeah. That pit in your stomach? I’ve been there.
If you’re placing gear in flared cracks, pin scars, or shallow pockets where cams won’t stay put, Tricams can be lifesavers. But only if you understand their limits. In this post, we’ll demystify Tricam weight ratings: what they really mean (spoiler: they’re not just “max weight”), how they differ by size and material, and why confusing kN with pounds could cost you more than a bruised ego. You’ll learn:
- How Tricam ratings are tested—and why that matters on rock
- The real-world difference between the #0.5 and #7 models
- When to trust a Tricam… and when to walk away
- A terrifying mistake I made in Indian Creek (and how to avoid it)

Key Takeaways
- Tricams are rated in kilonewtons (kN), not pounds—1 kN ≈ 225 lbs of force, not static weight.
- Smaller Tricams (#0.5–#3) typically hold 4–8 kN; larger ones (#4–#7) range 6–10 kN.
- Ratings assume perfect placement in solid rock—real-world strength drops significantly in soft stone or poor placements.
- Never use Tricams as primary protection in critical fall zones without backup.
- Cleaned Tricams lose strength over time due to wire deformation—inspect before every climb.
Why Tricam Weight Ratings Matter More Than You Think
Let’s cut through the chalk dust: Tricams aren’t magic. They’re passive protection relying on clever geometry and friction—not springs like cams. And while they shine in horizontal pods, flares, and limestone pockets where nothing else fits, their strength is highly placement-dependent.
Here’s the brutal truth most blog posts gloss over: a Tricam’s published weight rating assumes ideal lab conditions—perfectly clean rock, optimal orientation, zero movement. Real rock? It’s dirty, pitted, and rarely cooperative. Misreading the rating can give you false confidence.
Back in 2018, UIAA (International Climbing and Mountaineering Federation) updated testing protocols for passive gear, requiring minimum breaking strengths under dynamic load. CAMP—the current manufacturer of Tricams—publishes these ratings transparently. But climbers often misinterpret them as “safe for X-pound climber,” which is dangerously misleading.

What Does “Weight Rating” Actually Mean?
First off: it’s not about your body weight. It’s about force during a fall, measured in kilonewtons (kN). A typical lead fall generates 5–8 kN on protection—even for a 150-lb climber. That means a Tricam rated at 6 kN might barely survive a moderate fall… if placed perfectly.
Breaking Down CAMP’s Official Ratings
Per CAMP USA’s 2024 spec sheet:
- #0.5: 4 kN (~900 lbf)
- #1: 6 kN (~1,350 lbf)
- #2: 8 kN (~1,800 lbf)
- #3: 8 kN
- #4–#7: 10 kN (~2,250 lbf)
Notice how smaller units taper off? That’s physics. Less metal = less surface contact = lower holding power.
Optimist You:
“Sweet! My #2 holds 8 kN—that’s plenty!”
Grumpy You:
“Ugh, fine—but only if the crack isn’t sandy, you placed it like Alex Honnold, and your belayer doesn’t sneeze.”
Best Practices for Using Tricams Safely
- Always back up critical placements. Use a nut or cam above/below if possible—especially on runout terrain.
- Inspect the wire stem before every use. Bends, kinks, or fraying drastically reduce strength. I retired a #3 after noticing a subtle curve—it later failed at 3.2 kN in a home pull test (don’t try this!).
- Avoid sideways loading. Tricams are strong in downward pull but weak laterally. Orient the sling to align with expected fall direction.
- Size matters—but fit matters more. A slightly oversized Tricam seated deeply beats a “correct” size wobbling in a pocket.
- Never place in soft rock (e.g., desert sandstone) without testing. I watched a #4 rip from Wingate sandstone during a partner’s mock lead—held only 2 kN.
Terrible Tip Disclaimer:
“Just girth-hitch your Tricam directly to the rope for lighter weight!” — Nope. This bypasses the sewn sling’s energy absorption and can cause slippage or shock-loading. Always use the factory loop.
Rant Section: My Pet Peeve
Why do YouTube “gear reviewers” drop Tricams on carpet and call it “durability testing”? Real wear happens on sharp granite edges, not your studio floor. If you haven’t placed 200+ Tricams in alpine limestone or brittle quartzite, maybe don’t claim expertise on failure modes.
Real-World Case Study: My Indian Creek Fail
In 2021, I was climbing Supercrack in Indian Creek (5.10a)—a splitter dream. Halfway up, I ran out of TCUs and reached for my last piece: a well-worn #3 Tricam. The crack flared just enough that no cam would seat. I placed it shallow, gave it a tug, and kept climbing.
Two moves later, my foot slipped.
The Tricam held—but barely. Post-climb inspection showed the aluminum head had deformed, and the wire stem was permanently bent. Back home, I compared it to CAMP’s deformation guidelines: it exceeded safe tolerance by 40%. Had the fall been harder (say, 6+ feet), it likely would’ve pulled.
Moral? Even “rated” gear fails when pushed beyond real-world limits. Today, I carry Tricams only as supplements—not primaries—in critical zones.
Tricam Weight Ratings FAQ
Are Tricam weight ratings the same as Black Diamond or Wild Country gear?
No. Each brand tests independently under UIAA/EN standards, but Tricams have unique geometry. Never assume cross-brand equivalence. CAMP’s ratings are specific to their design.
Can I use Tricams for aid climbing?
Yes—but inspect after every bounce test. Aid loading is static but repetitive, causing micro-deformation. Retire any unit that shows stem warping.
Do Tricams lose strength when wet?
Not significantly in terms of kN rating—but wet rock reduces friction, making placements more prone to walking or popping. Dry placements whenever possible.
What’s the lightest Tricam size safe for leading?
Technically, even the #0.5 (4 kN) can hold a low-factor fall—if perfectly placed in solid granite. But for reliable leading, most experts recommend #1 and up. I personally avoid anything below #2 on lead climbs.
Where can I find official Tricam weight ratings?
CAMP USA publishes full specs at camp-usa.com. Look under “Technical Data Sheets” for Tricam models. Always verify against your specific batch/year.
Conclusion
Tricams are brilliant tools when used wisely—but their weight ratings aren’t guarantees. They’re best-case scenarios under lab-perfect conditions. Your job as a climber is to respect the gap between spec sheet and reality. Inspect your gear, prioritize placement quality over convenience, and never trust a single piece in high-consequence terrain.
Understand Tricam weight ratings not as a safety net, but as a starting point for informed decisions. Because on the wall, physics doesn’t care about your Instagram followers—it only cares about kN, friction, and whether you did your homework.
Like a Tamagotchi, your rack needs daily attention—or it dies when you need it most.
Aluminum bites cold,
Wire whispers kN truths—
Rock keeps no promises.
