Like massive cams

Changing the tightness of the lobes’ spiral can change both the cam’s range and its camming angle.

Like massive cams-81

Jardine, an aerospace engineer by training, had already been tinkering with new climbing gear for a couple of years when he first got a look at the Cam Nut in 1973.That means cam manufacturers have to strike a balance between the cam’s range and its holding power.2 These days, climbers tend to use the word “cam” to refer to SLCDs, but, technically, a cam is any tool that can transform linear motion (like a fall) into rotary motion (the rotation of a piece of pro to wedge it more firmly into place).That means hexes placed in a particular orientation, Tri-Cams, and even Big Bros qualify as cams, even though they have no springs.3 It’s not completely clear who first developed the idea of applying a curved camming surface—modeled on a logarithmic spiral—to climbing protection.Designed, manufactured and refined through repeated use on the big walls by a mechanical engineer, they are extremely smooth in operation and incredibly strong.These oversized spring-loaded camming devices (SLCDs) are perfect for Yosemite Valley, the Devil's Tower, Zion, Sedona, Squamish, Vedauwoo, and other wide crack meccas.
