Abstract
Abstract An anchor base for lighting or other standards has a cast construction including a hollow cylinder for receiving the standard and a generally square base supporting the cylinder. Four integrally cast buttresses extend from the base partway up the cylinder to strengthen the same. The base is open interiorally and slots for holddown bolts extend from outside of the cylinder through the base and through the cylinder and open into the open base. Stops are provided within the cylinder for limiting the telescoping movement of the standard.
