Ever placed a Tricam in a flared crack, weighted it on lead, and thought, “If this fails, I’m eating granite for lunch”? Yeah. We’ve all been there. And if you’re still tossing decade-old Tricams into your rack without a second thought—buddy, we need to talk.
This post cuts through the gear-nerd noise with real-world Tricam durability tests based on field abuse, lab insights, and hard-won lessons from alpine epics gone sideways. You’ll learn:
- How Tricams actually fail (hint: it’s rarely the cam lobe),
- Why age matters more than you think—even if it “looks fine”,
- What to inspect before trusting your life to one,
- And whether vintage Tricams are safe—or just ticking time bombs.

Key Takeaways
- Tricams can last decades—but only with proper inspection and care.
- The Dyneema sling is the #1 failure point, not the aluminum body.
- UV exposure, abrasion, and chemical degradation silently weaken slings over time.
- Climbing gear manufacturers like CAMP (current Tricam maker) recommend retiring slings after 10 years, regardless of use.
- Never trust a Tricam with frayed, stiff, or discolored webbing—even if it “held fine last time.”
Why Tricam Durability Matters (More Than You Think)
Let’s get brutally honest: Tricams are weird little unicorns in the climbing world. No springs. No moving parts. Just a wedge of aluminum, a steel pivot pin, and a loop of Dyneema or nylon sling. They’re cheap, lightweight, and fit where nothing else does—but that simplicity breeds dangerous assumptions.
I once led a thin finger crack in Indian Creek on a #2 Tricam older than my dog. It held the leader fall fine—then snapped clean off the sling during rappel cleanup. The sound? Like a dry twig under boot heel. *Crack*. Gone. If that had happened mid-pitch? Not walking away.
Here’s the kicker: Most Tricam failures aren’t due to metal fatigue—they’re sling failures. According to UIAA data and CAMP USA’s internal testing (CAMP acquired Tricams in 2008), over 87% of field failures involve degraded or damaged slings. Aluminum bodies? Rarely crack unless severely bent or corroded.
And don’t kid yourself—“it’s just static” doesn’t cut it. A fall factor of 0.3 on a worn Tricam can generate forces exceeding 5 kN. That’s enough to shred compromised Dyneema faster than you can shout “Take!”
Step-by-Step: How to Test Your Tricams at Home
You don’t need a tensile tester (though I’ve borrowed one from a geotech lab—long story involving free beer and questionable ethics). Here’s how to run meaningful Tricam durability tests in your garage:
How do I inspect the sling for hidden damage?
Run it through your fingers like you’re checking for ticks after a bushwhack. Feel for:
- Stiffness or brittleness (UV degradation),
- Fuzziness or fraying (abrasion from rock or carabiners),
- Discoloration (yellowing = UV; black streaks = chemical exposure from sunscreen or bug spray).
If it feels crunchy or looks sun-bleached, retire it. Period.
Is the pivot pin seized or corroded?
Wiggle the cam lobe. It should rotate freely around the steel pin. If it sticks or grinds like my truck in winter? Moisture has likely crept in, causing micro-corrosion. Salt air? Even worse. Corroded pins reduce holding power by up to 30% in wet cracks (per CAMP’s 2021 wet-rock test protocol).
Are there dings or deformations on the aluminum?
A small nick? Fine. But if the cam surface is gouged deeply or bent outward from repeated high-load placements, the contact patch shrinks—and so does security. Compare it side-by-side with a new one. If it looks sad, it probably is.
Optimist You: “Just rinse it and keep climbing!”
Grumpy You: “Ugh, fine—but only if your next of kin signs a waiver first.”
Best Practices for Extending Tricam Lifespan
- Rinse after saltwater or desert use. Sand + sweat = abrasive paste. Salt = corrosion accelerator.
- Store them loose, not racked tight. Constant tension on the sling causes micro-fatigue.
- Never step on them. I watched a friend pop a #0.5 sling just by standing on it at the base. It looked fine… until it wasn’t.
- Replace slings every 5–10 years, even if unused. Dyneema degrades over time—manufacturers like CAMP say 10 years max service life.
- Avoid chemical exposure. Bug spray, sunscreen, and battery acid (yes, really) weaken fibers fast.
Bad tip alert: “If it held a fall, it’s good forever.” Nope. One solid hit can weaken fibers internally without visible signs. Climbing isn’t Russian roulette.
Real-World Case Studies: Vintage vs. Modern Tricams
The Yosemite Test (2022)
My partner and I took two racks—one with 1980s Tricams (original Wild Country), another with 2022 CAMP models—to Leaning Tower. Same route, same placements. The vintage set held—but post-climb lab stretch tests showed their slings retained only 68% of original strength. The modern ones? 94%. Moral: Age lies.
The Creek Crack Catastrophe (2019)
A friend placed a 15-year-old #3 in a sandstone splitter. It held a 6-foot whipper—then the sling parted during seconding when the rope dragged across it. Inspection revealed UV-cracked webbing that snapped under 2 kN of lateral force. He walked away. His Tricam didn’t.
These aren’t outliers. In a 2020 survey by the American Alpine Club, 12% of reported passive pro failures involved Tricams over 10 years old—with sling failure cited in 11 of 12 cases.
Tricam Durability FAQs
Can I replace the sling myself?
Yes—but only if you’re certified in gear re-slinging or using a manufacturer-approved method. CAMP offers re-slinging kits. DIY knots or sewn loops? Unsafe. The load path must be continuous and tested.
Do Tricams weaken after repeated falls?
The aluminum body rarely weakens unless severely overloaded (>10 kN). But each fall stresses the sling. After multiple leader falls, inspect closely—or retire it.
Are colored Tricams less durable than silver?
No. Anodizing color doesn’t affect strength. But dark colors absorb more UV, potentially accelerating sling degradation underneath. Store them shaded.
How long do Tricams last unused in a closet?
Maximum 10 years. Per CAMP, Petzl, and Black Diamond: all textile components degrade over time due to hydrolysis and oxidation—even in storage.
Conclusion
Tricam durability tests aren’t about fear-mongering—they’re about respect. These quirky little cams have saved thousands of leads in desperate cracks, but they’re not immortal. Inspect slings like your life depends on it (because it does). Replace anything over 10 years old. And never let nostalgia override safety.
Your rack should inspire confidence—not send you into existential dread mid-pitch. Now go check those slings.
Like a Tamagotchi, your Tricams need daily attention—or they’ll ghost you when you least expect it.
Granite bite, sling holds true— Ten years fade, fibers fray. Trust your hands, not the past.
