US Patent 7313892 Support for manufactured housing

A pier cap for a disposition atop a pier of support for a structure, such as a manufactured home generally comprises a rectangular body having a generally flat planar textured top and support webs including a peripheral, downward extending wall and a plurality of internal webs and an open interior in the body between the webs.
