You’re halfway up a flared granite crack. Your cams won’t seat. Stoppers slide out with a whisper. Panic creeps in—until you remember the weird little piece clipped to your harness: the triple cam, or tricam. Most climbers treat them as obsolete relics. But when modern gear fails, that odd-shaped metal saves lives. Here’s what no retail spec sheet tells you.
Why Standard Protection Fails in Real Rock
Cams rely on parallel walls. Nuts demand constrictions. Nature rarely complies. Flared fissures, shallow pockets, and irregular pin scars laugh at textbook placements. And passive nuts? They rotate loose under load if the rock doesn’t perfectly pinch them.
The problem isn’t your skill—it’s your toolset. You’re trying to solve organic chaos with rigid geometry.

Tricams work differently. No springs. No moving parts. Just a clever fulcrum design that converts outward force into inward bite. Master them, and you unlock placements others walk past.
Selecting the Right Size for Variable Cracks
Tricams come in six standard sizes (0.125 to 3). The sweet spot? Sizes 0.5, 1, and 2 cover 80% of real-world scenarios. Forget color coding—learn actual dimensions. A #1 fits cracks from 19–25mm. Test with your pinky knuckle.
Active vs. Passive Placement Techniques
Passive mode = drop it in like a nut. Active mode = lever the head against one wall while the cam lobe bites the other. Active placements hold 2–3x more force—but only if the rock is solid enough to resist leverage.
Pro tip: In soft sandstone, go passive. In bullet-hard granite, crank it active.
Weight, Cost, and Reliability Compared
| Gear Type | Avg. Weight (g) | Cost per Unit ($) | Placement Speed | Failure Risk in Flared Cracks |
|---|---|---|---|---|
| Spring-loaded Cam (SLCD) | 120–180 | 65–110 | Fast | High |
| Wire Stopper (Nut) | 20–50 | 8–15 | Medium | Very High |
| Triple Cam (Tricam) | 40–70 | 25–40 | Slow* | Low |
*Placement speed improves dramatically with practice. After ten clean leads, you’ll slap tricams faster than fumbling with a stuck cam trigger.
The Industry Secret: Why Brands Don’t Push Tricams
Here’s the reality: tricams are low-margin, hard-to-explain gear. Retailers push cams because they’re flashy, expensive, and easy to demo in stores. Tricams? Require nuance. Climbing media ignores them—they don’t photograph well mid-fall.
But veteran alpine guides still carry them. Not as backup. As primary protection on routes like The Nose or Longs Peak’s Casual Route. Why? Because when the rack runs light and the rock runs weird, geometry wins over marketing.
And yes—some manufacturers quietly discontinued certain sizes not due to poor sales, but because the aluminum casting process was inconsistent. The surviving models? Over-engineered to compensate. That’s why older CCH tricams fetch collector prices.
Frequently Asked Questions
Are tricams safe for lead climbing?
Yes—if placed correctly. Active placements in solid rock exceed 8 kN strength. Always test with a firm tug before weighting.
Can I use a tricam in a horizontal break?
Rarely. They need vertical or near-vertical orientation to cam properly. In horizontals, they tend to walk or pop out under rope movement.
Why do some climbers call them “death cams”?
Misplaced fear. Early adopters used them incorrectly—passive in flared cracks without adequate constriction. Proper technique eliminates this risk.
