Abstract
A hand-held tool for spacing clapboards that includes a speed square tongue located in the top center of the device. This feature allows a user to quickly and accurately transfer both horizontal and vertical lines, revealing material to be removed around doors and windows. There is a trigger mounted on the ergonomic handle that both locks the tongue in place for transferring horizontal lines, and releases the tongue for transferring vertical lines. Two trays are adjustable in ¼″ increments that use pull pins under the trays. The trays can be adjusted for any board up to 10″ in height. Desired overlap is achieved by adjusting the position of the bottom tray as desired. Finally a ruler is provided along the side of the tool. A second model that has no handle is also taught.
