A deceptively simple-looking tool, the BoWrench is a must have for both professional builders and do-it-yourselfers. The BoWrench gives you a fast, one-person way to straighten decking boards. This is great, because decking material... whether redwood, cedar, or pressure treated pine... is often warped, especially in 12 to 16 foot lengths.
To operate the BoWrench, you simply slip the tool on a joist, pull the lever arm, and release. You can either push or pull boards into alignment, and when the handle is perpendicular, the tool locks in place, holding the board securely and leaving both hands free to drive nails or screws.
