The Black Diamond X4 Cams combine unparalleled expansion range, along with single-stem flexibility and an extremely narrow head width. The smallest three sizes of the X4 cams feature Black Diamond's Stacked Axle Technology, which uses a unique machined axle to give more expansion range per size than any other small four-cam unit available. The uniquely designed cams have embedded cam springs which allow for an ultra-narrow head width that fits in shallow cracks. The hot-forged trigger bar and symmetric swage allow easy racking and placement.
Double axle (.75, .5 and .4) and Stacked Axle Technology (.3, .2 and .1) provide huge expansion range
Narrower head width than original Camalot fits in more places than ever
Aluminum armor beads protect cable stem without compromising flexibility
Symmetric swage and hot-forged trigger bar eliminate buckling and provide ergonomic handling
