Bar clamp wolfcraft GmbH SZ 120-450 45 cm Black Grey

The wolfcraft SZ 120-450 bar clamp is a 45 cm clamping tool designed for woodworking and general assembly tasks. Finished in black and grey, this single unit provides a 120 mm depth and a robust galvanised cavity-profile clamp arm that resists bending under load. The clamp combines an ergonomically shaped handle with non-slip inserts and a galvanised spindle with trapezoidal thread to deliver consistent, controllable clamping force.

Advantages

The ergonomic handle with non-slip inserts enables efficient power transfer during tightening and reduces hand fatigue. A galvanised spindle with trapezoidal thread ensures smooth, reliable adjustment and secure clamping without slippage. The clamp arm profile is designed to remain straight under large spans, providing stability for glue-ups and assembly. Grooved edges on contact surfaces improve grip on workpieces, and the clamping arm can be used flat or rotated 90° to adapt to different working positions.

Suitable for

• Woodworking glue-ups and assemblies
• Holding parts steady during drilling or fastening
• General workshop clamping for carpentry and DIY projects

Key specifications

• Clamping opening: 45 cm
• Depth (jaw reach): 120 mm
• Material finish: black and grey with galvanised metal components
• Spindle type: galvanised spindle with trapezoidal thread
• Handle: ergonomically shaped with non-slip inserts
• Clamp arm: cavity-profile design to resist bending

How to use

Position the clamp so the jaws contact the workpieces to be joined, ensuring the grooved edges align with the material for a secure grip. Turn the ergonomically shaped handle to advance the galvanised spindle until the desired clamping pressure is achieved. For glue-ups, make final small adjustments to apply even pressure across the joint; the clamp arm can be laid flat on its upper part or rotated 90° and rested on its back to suit the workpiece orientation. Release the spindle by turning the handle in the opposite direction when work is complete.

Usage recommendations

Use multiple clamps spaced evenly for long or wide joints to ensure uniform pressure. Avoid over-tightening; apply only the pressure necessary to hold parts securely and to achieve proper adhesive contact. Store the clamp in a dry place to maintain the galvanised finish and function.
