Product details
Black Diamond Z4 Offset #.2/.3 Cam
The Black Diamond Z4 Offset #.2/.3 Cam is an ultralight micro offset trad climbing cam designed for secure protection in extremely thin, flared, and irregular crack systems. Featuring offset cam lobes and Black Diamond’s RigidFlex stem technology, it provides a precise balance of flexibility and stability, allowing reliable performance in marginal placements where standard cams may not seat securely. Ideal for delicate seams, pin scars, and technical trad climbing, this cam is part of a high-precision lightweight protection system built for demanding alpine and traditional climbing environments. This unit is unused but does not include original tags and may show minor cosmetic storage wear from handling and storage.
