Parallel Clamps Piher PRL 400, 60 cm bar, max 4000 N clamping force

Piher PRL 400 parallel clamps with a 60 cm bar deliver controlled, even clamping pressure for woodworking and assembly tasks. Designed to maintain parallel alignment of workpieces, these clamps offer a maximum clamping force of 4000 N and a robust construction that supports glue-ups, drilling and fitting operations. The tool is intended for situations where consistent pressure distribution and secure holding are required to ensure accurate joints and stable fixtures.

Advantages

These parallel clamps provide uniform pressure across the clamped surfaces to reduce distortion and improve joint accuracy. The 60 cm bar accommodates medium-sized assemblies while the high clamping force ensures strong, reliable holding for a variety of materials. The clamp design keeps the jaws parallel during tightening, improving alignment and minimizing slippage. Materials and mechanisms are chosen to offer durability and repeatable performance in workshop conditions.

Suitable for

• Gluing wood panels and frames
• Cabinet and joinery assembly
• Drilling and routing setups that require stable clamping
• Holding workpieces during sanding or finishing

Key specifications

• Bar length: 60 cm
• Maximum clamping force: 4000 N
• Parallel jaw design for even pressure distribution
• Suitable for woodworking and general workshop use

How to use

Position the clamp so the jaws fully contact the workpiece surfaces you intend to secure, ensuring alignment before applying pressure. Advance the movable jaw along the bar until it contacts the piece, then apply force using the clamp mechanism until the required holding pressure is reached. Check that the jaws remain parallel and that the workpiece is held without excessive deformation. For multiple clamps in a glue-up, apply them progressively and evenly to achieve uniform pressure across the assembly.

Usage recommendations

Use protective pads or scrap wood between the clamp jaws and delicate surfaces to prevent marking. For glue-ups, tighten gradually and allow recommended curing time before removing clamps. Inspect the clamp’s sliding and tightening mechanisms periodically and keep them free of heavy debris to maintain consistent performance.
