    This product is for…

    Trad climbers who want small cams (sizes 0–0.75) that fit shallow, narrow, or horizontal placements where a standard C4 won't go. Hosts consistently recommend them as a second set on a double rack in finger-sized pieces, sizes 0.3–0.75.

    Worth noting…

    Only available in sizes 0–0.75, so C4s are still needed for larger sizes. One host flags trigger wire durability as something to be mindful of, advising against frequent falls on small gear.

    Yes — Ben Lim recommends the Camalot™ Z4 by Black Diamond as their climbing protection pick. A nice refinement over the the C4 cams, the Z4's have smaller heads which allow them to fit in more placements. Love them.
