Bar Clamp Irwin PRO M 120 x 800 mm 10503572, adjustable screw clamp for woodworking

The Irwin PRO M 120 x 800 mm adjustable screw bar clamp is a tool for holding workpieces securely during woodworking, assembly and gluing operations. With a 120 mm throat depth and an 800 mm clamping span, this clamp provides a stable grip and allows precise pressure control via its screw mechanism, enabling accurate alignment and consistent joint pressure for carpentry and furniture work.

Advantages

The screw mechanism delivers fine control over clamping pressure, reducing the risk of over-compression while ensuring a firm hold. The 120 mm throat depth permits clamping further from the edge for mid-panel work, and the 800 mm span accommodates larger boards and assemblies. The clamp body and handle are designed for durable workshop use and repeated tightening cycles, providing consistent performance for routine woodworking tasks.

Suitable for

• Wood gluing and panel assembly
• Carpentry and joinery tasks requiring steady holding force
• Furniture assembly and repair
• General workshop clamping for cutting, sanding and routing

Key specifications

• Throat depth: 120 mm
• Clamping span (reach): 800 mm
• Clamping type: screw-adjustable bar clamp
• Intended applications: woodworking, assembly, gluing
• Handle style: screw/rotating handle for precise pressure control

How to use

Position the clamp so the jaws sit squarely on the workpiece surfaces to be joined or held. Turn the screw handle clockwise to increase clamping pressure until the parts are aligned and contact is even; avoid excessive torque to prevent material distortion. To release, turn the handle counterclockwise until the jaws loosen and the clamp can be removed. For larger assemblies, apply multiple clamps spaced evenly to distribute pressure across the joint.

Usage recommendations

Inspect the contact surfaces for debris before clamping and, when working with delicate or finished surfaces, use protective pads to prevent marking. Do not use the clamp as a lever or an anvil; maintain steady, controlled tightening for best results.
