Vaughan & Bushnell's BowJak provides a quick and simple solution for installing warped and crooked deck boards. Tapped in next to bowed or curved boards, the BowJak uses leverage from its pull handle to straighten the boards before they are secured. The tool can close gaps up to 2-1/4 inches wide, the maker says, and can be used horizontally, vertically, or overhead.
Cost: $38. 815-648-2446. www.vaughanmfg.com.
