Rockler 4-Way Equal Pressure Clamp

Adjustable length clamp provides pressure from all four sides, so it's ideal for big projects such as gluing table tops and shelving. To make wood pieces, drill a series of 5/8" holes spaced 2" apart down the centre line of the board face of a 2x4 piece of lumber. Then rip the board lengthwise through the centres of the holes, creating two pieces approximately 1-1/2" x 1-11/16". Rotate the notched boards so the notches are away from each other.
