Grampo em U Erdi LMU20/5 – abertura de aperto 20 cm, aço inoxidável, vermelho

The Erdi LMU20/5 U-clamp offers a 20 cm clamp opening in a compact stainless steel body with a red finish. Designed to hold, secure and align workpieces, this clamp features a U-shaped frame that distributes pressure evenly and allows step-over clamping to reach confined or recessed areas. Weighing approximately 290 g, it is suitable for woodworking, metalworking and assembly tasks where a medium-span clamping solution is required.

Advantages

The one-piece drawn steel rail provides durability and high strength while the U-shape enables step-over clamping up to 20 mm for access to hard-to-reach spots. A die-cast zinc sliding arm keeps the clamp light, stable and resistant to breakage. Protective caps are included to safeguard sensitive surfaces during clamping. The clamp delivers measured clamping force and compact handling for controlled, precise work.

Suitable for

• Woodworking tasks requiring medium-span clamping
• Metalworking fixtures and small assemblies
• Holding components during gluing or fastening
• Clamping in recessed or hard-to-reach positions

Key specifications

• Clamp opening: 200 mm
• Clamping force: up to 1,500 N
• Construction material: stainless steel rail, die-cast zinc sliding arm
• Step-over clamping capacity: up to 20 mm
• Protective caps: included (two)
• Weight: approx. 290 g
• Finish: red

How to use

Position the U-clamp so the workpieces sit inside the U-shaped frame and adjust the sliding arm until the protective caps contact the surfaces. Tighten to achieve the required clamping force, taking care not to overtighten sensitive materials. Use the step-over capability when clamping around edges or into recessed areas by engaging the rail at the required offset. Release the clamp by loosening the sliding arm and remove when the operation is complete.

Recommendations

For best results, inspect protective caps before use and replace if damaged. Apply even pressure and avoid excessive torque to preserve the clamp’s components and protect workpiece surfaces. Use appropriate personal protective equipment when working with tools and assemblies.
