ABSTRACT:
A combination speed and framing square includes first and second legs joined to form a right angle. The first and second legs are substantially longer than those found on a typical framing square allowing higher pitch roof rafters to be sequentially marked in increments of two feet. A third leg is attached to the first and second legs forming the hypotenuse of a right triangle with the first and second legs. The third leg has an elongated marking aperture with hip and valley and common rafter marking indicia on opposing sides thereof as well as incremental angular indicia adjacent its outer edge as with a typical speed square. Level indicators such as bubble levels are disposed on the first and second legs. At each end of the first leg and at a distal end of the second leg is an integral elongated slot each dimensioned to removably receive a rolling measuring device with a digital distance indication means on the exterior thereof. Accordingly, a distance may be quickly and easily measured by rolling the device along a surface and visually reading the display device.
