40" Parallel K Body Bar Clamp, 3-3/4" Throat Depth

40 Inch Parallel Bar Clamp For Precise Work

40 inch parallel bar clamp delivers secure clamping force up to 1,700 lb, so workpieces are held firmly during glue-ups and assembly when high pressure across wide faces matters. The clamp is designed to clamp at 90 degrees to the rail with very large clamping surfaces, which helps keep casework, panels, and frames square while distributing pressure over a broad area. A 3-3/4 inch throat depth extends the reach from the rail to the clamping face, allowing clamping deeper into assemblies or across thicker stock. The operating jaw stays where you put it for easy set up, so you can position jaws, stage parts, and then bring everything together without fighting jaw drift. Three removable pressure caps are resistant to glue, paint, and solvents, so adhesive squeeze-out and finishing residues do not bond permanently to the clamping faces, helping maintain consistent grip. This clamp is part of the K Body Revo design, built for demanding woodworking.

Key Parallel Clamp Details That Aid Workflow

• Secure clamping force up to 1,700 lb applies substantial pressure across joints, which matters for tight glue lines and stable assemblies in larger casework or panel work where even compression is critical.
• Clamping at 90 degrees to the rail with very large clamping surfaces keeps pressure applied square to the work, helping reduce racking in cabinets, doors, and frames during dry fits and glue-ups.
• Ergonomic two component handle with a steel socket for applying force with a hex key or driver (max torque 17 Nm) lets you apply clamping pressure by hand or with a driver when additional leverage is needed in repetitive or heavier setups.
• The operating jaw that stays where you put it supports easy set up, letting you stage the moving jaw near final position on the rail so positioning multiple clamps along a run is quicker.
• Two work piece supports prevent the clamped material from contacting the steel rail, helping keep finished edges off the rail surface and reducing transfer of contaminants onto workpieces.

Installation And Adjustment On The Rail

The clamp converts to spreading with no tools required in seconds by removing the end stop and reversing the operating head, so you can switch from compressing to pushing parts apart without changing tools. For smooth opening, releasing any clamping pressure in place, then pivoting the handle up and away from the rail before sliding the operating jaw, keeps movement along the rail controlled when increasing the opening. For closing and clamping, pivoting the handle towards the rail, sliding the jaw to the work piece, and then beginning clamping uses the handle orientation as part of the engagement, so the jaw advances efficiently into position. The ergonomic two component handle with a steel socket for hex key or driver input up to 17 Nm lets installers dial in predictable pressure on repeated setups. The operating jaw stability along the rail supports accurate placement before final tightening in either clamping or spreading mode.

Using The KRE3540 Clamp In Woodworking Projects

Where This 40 Inch Parallel Clamp Performs

This parallel clamp is categorized under woodworking tools and equipment, hand tools, and clamps, so it is suited to bench work where controlled manual clamping is central to the process. Secure clamping force up to 1,700 lb supports tasks like panel lamination and carcass assembly where strong, even pressure across joints is needed for consistent bonding. The design clamps at 90 degrees to the rail with very large clamping surfaces, which helps maintain squareness on cabinet sides, door assemblies, and frame components by keeping pressure aligned with the faces instead of concentrating at a point. A 3-3/4 inch throat depth allows the jaw faces to reach farther from the rail, making it practical when clamping deeper boxes or wider frames where a shallow reach would not contact the desired area. Two work piece supports lift material off the steel rail, which helps keep reference faces away from the rail surface during assembly layouts.

Details That Support Repeatable Results And Setup

The operating jaw that stays where you put it for easy set up allows pre-positioning multiple clamps along a project, improving repeatability when identical parts must be clamped in the same locations. Three removable pressure caps resistant to glue, paint, and solvents keep buildup off the contact faces, supporting consistent friction and contact quality across many cycles of use. The ergonomic two component handle with its steel socket for applying force with a hex key or driver up to 17 Nm offers a defined way to reach higher forces without over-gripping, which supports stable, repeatable torque application on production-style runs. The ability to convert to spreading quickly by removing the end stop and reversing the operating head lets the same tool handle separation tasks, such as pressing frames outward or aligning components from the inside, keeping workflows more streamlined. Clear motions for opening by pivoting the handle up and away from the rail, then sliding the jaw, and for closing by pivoting the handle towards the rail, sliding to the work piece, and beginning clamping, give installers a repeatable sequence that can be followed across multiple clamps to keep timing and pressure application consistent.
