Build a better patio yourself with the CAMO LEVER, a single-turn tool for securing rows of boards and clamping and straightening warped boards. It easily adjusts to fit single, double and metal beams 1.5 to 3 inches wide and works at any angle. The device locks rows of planks and clamps, speeding up the installation of the fluted patio while maintaining a consistent spacing. With ample strength, the tool effortlessly straightens warped boards from unruly, pressure-treated to dense hardwood. The multi-directional handle locks into place with a single turn, providing powerful torque with minimal effort.
