F-clamp Bessey GZ20 — 20 cm opening, aluminium bar, red handle

Bessey GZ20 is an F-clamp with a 20 cm opening, featuring an aluminium bar and a red handle. It is designed for holding, gluing and assembly tasks in woodworking and general workshop environments. With a compact form factor and a corrosion-resistant aluminium bar, the clamp is intended to provide stable pressure for light to medium clamping duties while remaining easy to position and adjust.

Advantages

The aluminium bar reduces weight and resists rust, making the clamp easier to handle and suitable for humid workshop conditions. The 20 cm opening gives sufficient reach for medium-sized workpieces, while the ergonomically shaped red handle enables comfortable tightening and controlled pressure application. Its compact construction allows for use in confined spaces and simplifies storage when not in use.

Suitable for

• Woodworking assembly and glue-ups
• Light to medium workshop clamping tasks
• Holding parts during cutting, drilling or sanding
• General DIY repair and assembly projects

Key specifications

• Maximum opening: 20 cm
• Bar material: aluminium (corrosion-resistant)
• Handle: ergonomic red handle for manual tightening
• Weight: approximately 950 g
• Clamp type: F-clamp (bar clamp) suitable for single-hand operation

How to use

Position the clamp with the fixed jaw against one side of the workpiece and adjust the sliding jaw along the aluminium bar until it contacts the opposite side. Use the red handle to tighten the clamp until the required holding pressure is achieved; apply steady, controlled force to avoid over-tightening. To release, loosen the handle and slide the movable jaw away from the workpiece. The lightweight aluminium bar makes repositioning straightforward for repeated clamping steps.

Usage recommendations

For even pressure distribution during glue-ups, protect finished surfaces with thin scrap boards or pads between the clamp jaws and the workpiece. Avoid exposing the clamp to strong solvents or continuous salt spray; occasional cleaning and light lubrication of moving parts will maintain smooth operation. Use this clamp within its intended light to medium duty range to ensure safe and reliable performance.
