Karabiner, medium, 8,9 cm, uten lås

Smooth action on the gate and a solid click when it closes—exactly what I wanted for clipping my keys to a belt loop. The 3.5-inch size is compact enough to not snag on stuff.

Nearly the exact size I needed for my dog leash and keys, and the spring action is smooth right out of the package. Withstood a few rough tugs this week without any sign of wear.

I clipped this onto my work belt to hold my keys and a small utility line, and the 3.5-inch size is just right—not bulky, but it grips everything securely. The spring action is smooth and firm, so nothing has slipped off even when I'm moving around.
