Abstract: A wood sill reinforcing plate for use with anchor bolts embedded in a concrete foundation and extending upward and a wood sill having openings which receive the outwardly extending anchor bolts. A plate member having an opening extending through the plate member and with the opening having a dimension slightly larger than the diameter of the anchor bolt. A plurality of gripper prongs integral with the plate member and extending in a direction substantially perpendicular to the plate member for embedding the gripper prongs into the wood sill to lock the plate member around the anchor bolt with the anchor bolt extending through the opening in the plate member.

Abstract: A retrofit foundation system for bolting a sill plate to a foundation including, an upper piece member having a first upper portion for lying against the sill plate for bolting to the side of the sill plate and having a second portion extending outwardly from the side of the sill plate along the top of the foundation and extending past a side wall of the foundation. A lower piece member has a first lower portion for lying against the side of the foundation for bolting to the side of the foundation and has a second portion extending outwardly from the side of the foundation at the top of the foundation and with the outwardly extending portions of the upper piece member and the lower piece member lying adjacent to each other along a plane substantially parallel to the top of the foundation. The outwardly extending portions of the upper and lower piece members are attached together to transfer any external forces from the sill plate to the foundation.
