The Deck Devil is the most versatile board straightener you will find. It's a telescopic compact device that attaches to any handheld cordless drill (3⁄8” chuck) to deliver precise push or pull power to straighten any type of board. It allows you to get into tighter spaces for things like straightening boards, compressing bowed joists down onto supporting beams, and pulling fascia boards around curves. Consider the Deck Devil as essentially your third hand on the job site! See how the Deck Devil works here.
