Clamping Screw Light Erdi LMU 100x50 mm - BY (LMU10/5) hand clamp

The Erdi LMU 100x50 mm light screw clamp (model BY LMU10/5) is a compact, hand-operated clamping tool intended for light-duty holding tasks. It features a 100 mm maximum jaw span and a 50 mm throat depth, providing a stable grip for small workpieces. The screw drive allows controlled, gradual tightening and fine adjustment of clamping pressure for repeatable positioning during woodworking, assembly and hobby operations.

Advantages

This light screw clamp combines a compact footprint with straightforward screw mechanics to deliver reliable holding force where large clamps would be impractical. Its manual operation requires no power source and enables precise pressure control. The 100 mm span and 50 mm throat depth make it suitable for clamping narrow boards, fixtures and parts in confined workspaces. The design supports repeatable setups and simple maintenance.

Suitable for

• Light woodworking tasks such as gluing, sanding and small joinery
• Assembly of small components and fixtures
• Hobby and craft projects where compact clamping is needed
• Temporary holding during drilling, filing or measuring operations

Key specifications

• Maximum jaw span: 100 mm
• Throat depth: 50 mm
• Operation: manual screw drive
• Intended use: light-duty clamping and holding
• Suitable materials: wood, soft metals, plastics and composite parts of small size

How to use

Position the clamp so the jaws align with the workpiece and ensure the throat depth accommodates the part. Turn the screw handle clockwise to close the jaws until the workpiece is held securely without over-tightening. For removal, turn the screw handle counterclockwise to release the pressure and open the jaws. Adjust clamping pressure incrementally to avoid damage to delicate surfaces and to achieve accurate alignment for repeatable setups.

Usage recommendations

Inspect mating surfaces for debris before clamping and, when necessary, use protective pads between the clamp jaws and the workpiece to prevent marking. Regularly check the screw thread for wear and apply light lubrication to maintain smooth operation. Select this clamp for tasks requiring a compact, manually controlled holding solution.
