Rope clamp for rope access. Excellent ability to block out particularly on muddy and icy ropes thanks to the holes on the cam and on the side plate. The new material and a special chemical and thermal process give to the cam, in addition to black color, a much higher surface hardness. The result is a great wear resistance and a reduction of the fragility that usually penalizes steels by quenching to low temperatures. New opening lever, ergonomic, easy to handle and protected from shocks and from the risk of accidental opening. Fitted with anti-overturning system of the cam.
