Bar Clamp Topex 4000 x 25 x 1 mm 12A340 — clamping bar for woodworking and assembly

The Topex bar clamp 12A340 (4000 x 25 x 1 mm) is a long, rigid clamping bar designed for woodworking and assembly tasks that require extended reach and uniform pressure. It is intended to hold workpieces in position during gluing, joining and alignment operations, providing linear clamping across long boards, panels and frames. The clamp suits workshop and on-site use where temporary but firm fixation is necessary for accurate assembly.

Advantages

The clamping bar offers a straight, stable platform to apply even pressure along the length of a workpiece, reducing movement during adhesive curing and mechanical joining. Its long span enables handling of large panels and assembled frames without the need for multiple shorter clamps. The design facilitates straightforward adjustment and secure holding while minimising the number of contact points that could interfere with surface work.

Suitable for

• Gluing long boards and panels
• Assembling door and window frames
• Edge alignment for laminate and veneering work
• Temporary fixation during cutting or routing of large workpieces

Key specifications

• Effective length: 4000 mm
• Bar width: 25 mm
• Bar thickness: 1 mm
• Material: rigid metal bar suitable for transmitting linear clamping force
• Designed for woodworking and assembly applications requiring extended reach

How to use

Position the bar clamp so the workpiece is aligned between the clamping faces, then advance the movable jaw or clamping mechanism until the desired pressure is achieved. Check alignment and make incremental adjustments to ensure even contact across the workpiece. Maintain clamping pressure for the full duration required by the adhesive or assembly procedure. Release the clamp only after the joint or glue has developed sufficient strength.

Usage recommendations

For reliable results, protect finished surfaces with thin pads where the clamp contacts the workpiece to prevent marring. Use multiple clamps or supports when working near the maximum span to distribute pressure evenly. Inspect the bar for straightness before use and avoid applying torque or side loads that could deform the bar.
