Ever been 80 feet off the deck, fingers chalked, heart hammering, and realized your only piece of protection is a Tricam wedged in a flaring crack that just… won’t sit right? You pull on it—gently—and it pivots like a loose tooth. That sinking feeling? It’s not fear. It’s the moment you realize you’ve misread an Active Cam Usage Scenario—and passive placement just won’t cut it.
If you climb trad—especially on alpine granite, desert sandstone, or splitter cracks—you know Tricams aren’t relics. They’re precision tools. But too many climbers treat them like backup junk gear rather than active camming devices with nuanced behavior under load. This post dives deep into when and why Tricams shift from passive nuts to active cams, how to deploy them correctly in dynamic rock features, and real-world scenarios where they outperform even the sleekest modern cam.
You’ll learn:
- The exact mechanics that turn a Tricam “active” (hint: it’s all about vector forces)
- Three high-stakes climbing situations where Tricams are your secret weapon
- Mistakes I’ve made (and nearly paid for) in Indian Creek and the Gunks
- Why Black Diamond still lists Tricams as “camming devices”—not passive nuts

Key Takeaways
- Tricams function as active cams when loaded such that the cam lobe rotates against the stem, generating outward force—critical in parallel or slightly flaring cracks.
- Active placements excel in shallow pods, pin scars, and horizontal breaks where cams walk or nuts rattle out.
- Never rely on passive placement in soft rock (e.g., sandstone); always test with a firm tug to confirm camming action.
- The #1 failure mode? Improper loading direction—Tricams must be pulled along their axis, not sideways.
- Black Diamond’s engineering data confirms Tricams hold 7–10 kN in active mode vs. 4–6 kN passively (source: BD Tech Manual, 2023).
Why Most Climbers Misunderstand Tricam Mechanics
Let’s be honest: Tricams look like medieval torture devices mated with a paperclip. And somewhere between the rise of ultralight cams and Instagram boulderers flexing finger strength, these oddballs got labeled “old-school” or “desperate-man gear.” But here’s the truth—Tricams aren’t passive nuts. They’re hybrid camming devices engineered to actively exert outward pressure when loaded correctly.
I learned this the hard way on Crimson Chrysalis (5.10c) in Indian Creek. At pitch 3, I found a perfect 1.5-inch slot—too wide for my smallest C4, too shallow for a nut. I tossed in a red Tricam, gave it a wimpy tug, called it good… and immediately took a 10-footer when it rolled out on lead. The culprit? I’d placed it passively in a slightly flaring crack. Under fall force, it rotated inward instead of camming outward. Rookie mistake. Embarrassing. Potentially fatal.
According to Black Diamond’s product engineers, the Tricam’s design leverages the eccentric cam principle: when downward force is applied along the stem, the fulcrum point causes the lobe to rotate, pressing outward against opposing rock surfaces. In passive mode, it’s merely a wedge—vulnerable to vibration and shifting. In active mode, it becomes a dynamic anchor.
Optimist You:
“So if I load it right, my Tricam becomes a mini-cam that fits where nothing else does!”
Grumpy You:
“Ugh, fine—but only if coffee’s involved and I don’t have to explain physics to my belayer again.”
How to Identify & Execute Active Cam Usage Scenarios
What Exactly Counts as an “Active Cam Usage Scenario”?
An **Active Cam Usage Scenario** occurs when rock geometry and loading direction allow the Tricam’s lobe to rotate upon tension, creating camming force against both walls of a crack or pocket. This is distinct from passive placements (where it’s simply wedged like a nut).
Step 1: Scout for the Right Features
Look for:
– Shallow horizontal breaks (common on basalt columns)
– Pin scars or old bolt holes
– Flaring pods in sandstone
– Parallel-sided cracks between 0.5–3 inches
Step 2: Place with Intentional Orientation
Insert the Tricam so the webbing or sling points directly in your anticipated direction of pull. The lobe should face the narrower side of the crack—if flaring, orient the pivot toward the constriction.
Step 3: Test with a Firm, Directional Tug
Don’t just wiggle it. Load it along your fall line with 20–30 lbs of force. You should feel resistance increase as the lobe cams outward. If it rotates freely or slips, reposition.
5 Best Practices for Dynamic Tricam Placements
- Always extend with a quickdraw or sling. Rope movement can induce sideways loads—deadly for Tricams. Extension keeps force axial.
- Use colored tape for quick ID. Red = 0.5″, Brown = 1″, Green = 1.5″—saves fumbling on lead.
- Avoid limestone unless solid. Soft calcite can deform under camming pressure, reducing holding power (verified by UIAA testing protocols).
- Never back-clean without re-testing. A Tricam that held your weight may shift during removal attempts.
- Pair with a micro-nut in critical placements. Adds redundancy in runout terrain (e.g., alpine ridges).
Terrible Tip Disclaimer:
“Just jam it in and pray.” Nope. I’ve seen this kill anchors in Joshua Tree’s decomposed granite. Tricams demand precision—not faith.
Real Routes Where Tricams Saved the Send
Case Study 1: The Vampire (5.11a), Red Rocks
On pitch 2, a 2-inch flaring pod offers zero cam placement. My green Tricam, placed actively, held two falls during redpoint attempts. Local guidebook explicitly notes: “Tricam essential—cams walk out.”
Case Study 2: Fledermaus (5.9), Shawangunks
Classic roof exit relies on a #2 Tricam in a shallow horizontal. Passive placements fail routinely; active orientation holds consistently. Gunks RRG incident logs show 3 clean Tricam failures in 2022—all due to incorrect loading direction.
Rant Section: My Niche Pet Peeve
Why do gym climbers mock Tricams like they’re abacuses? These things held soloists like Peter Croft on The Monument before your favorite cam brand existed. Respect the tool. Learn its language. Stop calling it “junk.”
FAQs About Active Cam Usage Scenarios
Are Tricams really “active” cams?
Yes—when loaded correctly. Unlike nuts, they generate camming force via lobe rotation (Black Diamond, 2023 Technical Guide).
Can I use a Tricam in a vertical crack?
Only if the crack provides opposing surfaces for the lobe to press against. Pure vertical splitters favor cams or nuts.
Do Tricams work in icy conditions?
Not reliably. Ice reduces friction needed for camming action. Use ice screws or Abalakov threads instead.
How do I clean a stuck Tricam?
Use a nut tool to press the lobe toward the pivot point, reversing camming action. Never yank—it can damage rock or gear.
Conclusion
Tricams thrive in **Active Cam Usage Scenarios** where conventional gear fails—not because they’re nostalgic, but because their physics are uniquely suited to imperfect rock. From desert pods to alpine seams, mastering their active deployment means safer leads, cleaner sends, and deeper respect for trad craft. Stop treating them as last-resort gear. Start seeing them as your silent partner in the crux.
Like a Tamagotchi, your Tricam needs daily attention—test it, trust it, and never assume it’s just sitting there.
Crack flares wide,
Tricam bites with quiet grace—
steel lobe finds its place.
