1. Product Overview
The Rockler Deluxe Parallel Clamps are designed to assist woodworkers in achieving perfectly flat panels and flush joints during gluing operations. These clamps utilize rigid steel cauls to sandwich the panel, ensuring alignment and preventing buckling. The innovative four-way pressure system applies force both horizontally to squeeze glue joints and vertically to hold boards flat, significantly reducing the need for extensive post-gluing sanding.

3. Setup and Adjustment
The Rockler Deluxe Parallel Clamps are designed for easy adjustment to accommodate various woodworking projects. They can clamp stock from 3/4 inch to 3 inches thick and panels from 10 inches to 36 inches wide. The thick steel construction and scissor-action couplers ensure durability and effective clamping for items such as table tops, wide door panels, and thick bench tops.
- Prepare Your Workpiece: Ensure your wood panels are properly prepared for gluing, with clean and flat edges.
- Position Clamp Rails: Place the clamp rails on a stable, flat workbench. The included clamp feet provide clearance for easier adjustment and repositioning.
- Adjust for Thickness: Adjust the clamp headstock and tailstock to the approximate thickness of your panel. The scissor-action couplers allow for quick and precise adjustments.
- Insert Panel: Carefully position your panel between the clamp rails.

4. Operating Instructions
Follow these steps for effective operation of your Rockler Deluxe Parallel Clamps to ensure flat and flush panel glue-ups:
- Apply Glue: Apply an even layer of wood glue to the mating edges of your panel pieces.
- Assemble Panel: Carefully bring the glued edges together to form your panel.
- Position in Clamps: Place the assembled panel between the adjusted clamp rails. Ensure the panel is centered and supported.
- Apply Pressure: Engage the scissor-action couplers and begin tightening the clamp handle. The four-way pressure system will simultaneously squeeze the glue joints together and apply downward pressure to keep the boards flat.
- Check Alignment: Verify that the panel is aligned and all joints are flush. Make minor adjustments if necessary before fully tightening.
- Curing Time: Allow the glue to cure completely according to the glue manufacturer's instructions before removing the clamps.
- Remove Clamps: Once the glue is fully cured, loosen the clamp handles and carefully remove the clamps from the panel.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Rockler Deluxe Parallel Clamps:
- Cleaning: After each use, wipe down the clamp rails and mechanisms to remove any glue residue or sawdust. A damp cloth can be used, followed by a dry cloth.
- Lubrication: Periodically apply a light lubricant to the screw threads and moving parts of the headstock and tailstock to ensure smooth operation.
- Inspection: Regularly inspect the clamps for any signs of wear, damage, or loose components. Address any issues promptly to prevent further damage or compromised performance.
- Storage: Store the clamps in a dry environment to prevent rust and corrosion.
6. Troubleshooting
If you encounter issues while using your Rockler Deluxe Parallel Clamps, consider the following:
- Panel Not Flat: Ensure sufficient downward pressure is applied. Check that the clamp feet are properly positioned and that the workpiece thickness is within the clamp's specified range. Using additional clamps for wider panels can also help.
- Joints Not Flush: Verify that the mating edges of your wood pieces are perfectly straight and clean before applying glue. Ensure even pressure is applied across the entire joint.
- Difficulty Adjusting: Check for any debris or glue residue in the adjustment mechanisms. Lubricate moving parts if they feel stiff.
- Clamp Slipping: Ensure the workpiece is securely seated in the clamp and that the tightening handle is fully engaged.
