ABSTRACT:
A concrete post assembly and method of mounting same. The post assembly is supported in upright position by an inground pier in which a plurality of anchor bolts are embedded with a portion of each bolt extending upwardly above the upper surface of the pier. The post assembly includes a concrete post and a base plate rigidly secured to the bottom of the post, the base plate having a plurality of holes located so as to register with upwardly extending anchor bolts. A nut is threaded onto each anchor bolt and the post assembly is mounted on the bolts with its base plate resting on the nuts which can then be adjusted to level the plate. A second set of nuts are threaded onto the anchor bolts and tightened against the upper surface of the base plate to lock the post assembly in mounted position.
