Black Diamond Camalot Z4 - 0.4 Single Stem Camming Device

With a 15.6 to 26.2 mm expansion range packed into a single-stem package, the Camalot Z4 0.4 delivers the secure placements trad climbers demand from Black Diamond's most advanced camming device line.

Overview

The Black Diamond Camalot Z4 0.4 is a single-stem, four-lobe camming device engineered for traditional, aid, and alpine climbing. Its narrow head width and flexible OmniFlex cable stem allow it to fit into shallow, irregular cracks where rigid-stem cams simply won't go. Sandblasted aluminum lobes bite confidently into rock, while the ergonomic trigger and Dyneema sling make one-handed placements quick and reliable.

What stands out

• OmniFlex cable stem bends and flexes to reduce walking and improve placement in flaring cracks
• Sandblasted lobes increase friction for a more secure grip on smooth or slippery rock
• Narrow head profile fits constrictions and shallow seams that other cams can't protect
• Ergonomic trigger with optimized thumb loop for easy handling, even with gloves
• Color-coded purple sling and lobe accents for instant size identification on your rack

Our verdict

The Camalot Z4 0.4 is the go-to micro-cam for technical trad pitches where every millimeter of placement matters. Its flexible stem and narrow head open up protection options that rigid cams can't match, while the sandblasted lobes inspire confidence on less-than-perfect rock.
