  • Patent number: 7984541
    Abstract: An anchor bolt template for use with cardboard molds used to form concrete into footings and other foundations. The template is integrally formed of plastic or some other resilient, light weight material. The most common bolt configuration includes four bolts spaced equal distances from the foundation's center. Thus, the preferred template shape is four arms extending radially from a hub. Each of the arms has bolt location markers labeled with the diameters of several bolt patterns. The arms may be generally C-shaped in cross section so that the depending edges ride on the upper edge of the mold, supporting the lower anchor bolt nut above the concrete. Notches, preferably labeled by mold size, on the bottom of the depending edges of the arms receive the upper edge of the mold so that as heavy concrete is poured into the cardboard mold the sidewall of the mold will not deform.
