Schroefklem wolfcraft GmbH SZ 120-300 30 cm zwart grijs

The wolfcraft GmbH SZ 120-300 bar clamp (30 cm) combines a classic clamping concept with an updated functional design. It has an ergonomic handle with non-slip inserts and a galvanised spindle with trapezoidal thread for reliable power transfer. The clamp arm is made from a high-quality galvanised cavity profile that resists bending at large spans. The new clamping-arm design allows the tool to be laid flat on the arm or on its back when rotated 90°; packaging includes a hang tag.

Advantages

The ergonomically formed handle with non-slip inserts improves grip and reduces slippage while applying force. A galvanised spindle with trapezoidal thread ensures precise and efficient transmission of clamping force. Grooved edges provide a secure hold that prevents the clamp from slipping or coming undone. The cavity-profile clamp arm is robust and remains straight even under long-span loads, making the clamp especially suitable for tasks requiring consistent pressure. The design also supports convenient positioning during glueing and assembly work.

Suitable for

• Woodworking and furniture assembly
• Glueing and bonding operations
• DIY projects and general workshop clamping
• Holding workpieces at spans up to the clamp's maximum opening

How to use

Open the clamp to the required span by turning the handle and position the workpiece between the clamp arm and the sliding jaw. Turn the handle clockwise to advance the spindle and apply pressure until the workpiece is held securely. For glueing, position the clamp so the upper part of the arm supports the tool flat, or rotate the clamp 90° to rest it on its back for better access. Release pressure by turning the handle counterclockwise and remove the clamp when the joint or assembly is set.

Recommendations

Use the glove-protected ergonomic handle and avoid over-tightening to prevent damage to delicate workpieces. For even pressure distribution on softer materials, add protective pads between the clamp jaws and the workpiece. Regularly inspect the galvanised spindle and clamp arm for wear or deformation before use.
