Small multi-purpose blocker designed for caving and all caving applications such as rescue, lining rescue, height works, canyoning. Uses all the latest generation ST i CA components of Kong blockers. The ability to lock on particularly muddy strings thanks to the emptying loops on the cam. The new material and a special heat and chemical process give the toothed cam, in addition to the black colour, a much higher surface hardness. The result is a great resistance to wear and a reduction in fragility that usually penalises hardening steels at low temperatures. Ergonomic opening clutch and easy to maneuver, very protected from bumps and the risk of accidental openings. Quality product, made in Italy.
