These sturdy 12-in x 16-in brackets are great for storing lots of long heavy clamps in a narrow space. The 2x4 brackets are wide enough for pipe and bar clamps. Use 2x6s to store K-body-style and deep throated adustable clamps. Dado a 45-degree support board into each bracket. Screw the brackets to the cleats from the back, leaving 2-in spaces between for the clamp's bars. Then fasten the brackets to the wall.
