Clamping Bar / Quick Clamp JOBIextra JOBI EXTRA 300 mm WX3662

JOBIextra JOBI EXTRA quick clamp with 300 mm clamping capacity (model WX3662) is a hand-operated clamping bar intended for securing workpieces during woodworking, gluing, assembly and light metalworking. The clamp provides a 300 mm usable span and a rapid-action mechanism that allows quick adjustment and application of firm holding pressure. Its straightforward design makes it suitable for both DIY enthusiasts and professional bench tasks where a reliable temporary hold is required.

Advantages

The quick-action mechanism enables fast positioning and tightening without the need for continuous turning, saving time when working on repetitive clamping tasks. The fixed bar and movable jaw are constructed to deliver stable, even pressure across the clamping area, reducing the risk of slippage during glue setting or assembly. The compact 300 mm span offers a balance between portability and holding capacity, making the clamp easy to handle and store while still covering a wide range of common workshop jobs.

Suitable for

• Securing boards and panels during glue-ups in woodworking
• Temporary holding for assembly and fastening tasks
• Light metalworking where moderate clamping pressure is sufficient
• DIY projects, repairs and hobbyist bench work

Key specifications

• Clamping span: 300 mm usable capacity
• Operation: hand-operated rapid-action mechanism for quick adjustment
• Jaw type: fixed bar with movable jaw for progressive tightening
• Intended use: woodworking, gluing, assembly, light metalworking
• Form factor: bar-style clamp for bench and portable use

How to use

Position the clamp so the fixed bar rests against one side of the workpiece and the movable jaw faces the opposite side. Squeeze the rapid-action handle or actuating element to slide the movable jaw toward the workpiece until initial contact is made, then engage the clamping mechanism to apply firm pressure. Ensure the workpiece is properly aligned before applying final clamping force. Release by disengaging the quick-action lever or mechanism and slide the movable jaw away from the workpiece. Use protective pads between the clamp jaws and delicate surfaces to avoid marking or denting.

Usage recommendations

For consistent results during glue-ups, use multiple clamps spaced evenly along the joint and tighten progressively to distribute pressure. Avoid exceeding moderate force suitable for the clamp’s bar design; for heavy-duty clamping needs, select a larger or dedicated heavy-duty clamp. Keep the sliding bar clean and free of debris to maintain smooth rapid-action performance.
