Rockler 4-Way Equal Pressure Clamp Hardware

Applies pressure from all four sides—ideal for keeping large glue-ups like table tops flat while the glue cures. Pair with your own shop-made wood strips to create a clamp of any length. To make the wood pieces, drill a series of 5/8'' holes spaced 2'' apart down the center line of the broad face of a 2x4. Then rip the board lengthwise through the centers of the holes, creating two pieces approximately 1-1/2'' x 1-11/16''. Rotate the notched boards so that notches are away from each other.

Features:

Applies pressure on workpiece face when edge-clamping to prevent bowing and buckling large panels
Clamp attaches to any length of 2 x 2 (lumber and wood clamp pads not included)
One clamp per package (each clamp includes 2 main components)
