Clamps made from high-quality cast iron. They feature a pressure arm with specially machined threads, made from A3 steel and finished with a zinc coating. The body also has additional ribs to increase structural strength. The surface is protected from corrosion with a powder coating. The pressure arm includes a movable pin that secures to prevent it from falling, allowing for a very strong clamping of the held material. The frame is highly resistant to torsion and vibrations. The large surface pressure plate, made of metal, is mounted on a ball, facilitating precise adjustment of the clamp on the material's surface. The C-type clamp, due to its design, is one of the strongest clamps, making it suitable for extreme industrial and construction conditions. It is commonly used in assembling heavy metal structures, carpentry, roofing, and often in welding operations.

• Purpose / application: For effective, very strong clamping of various materials.
