4-Way Equal Pressure Bar Clamp
Adjustable length clamp provides pressure from all four sides, eliminating the cupping that occurs with traditional clamps. Uses any length of 2x2 material (lumber and wood clamp pads not included), making them ideal for gluing up the largest table tops and panels. Includes two parts, enough for one clamp.To make wood pieces, drill a series of 5/8" holes spaced 2" apart down the center of the broad face of a 2x4 piece of lumber. Then rip the board lengthwise through the centers of the holes, creating two pieces approx. 1-1/2" x 1-11/16". Rotate the notched boards so that notches are away from each other.
