Abstract: A polymeric cradle having a base with a rectangular receiving surface emulating the surface of a brick. From the center of this receiving surface there extends a valve receptor of generally hexagonal cross section formed with oppositely disposed valve receiving mouths and generally oppositely disposed standards functioning to align the cradle within the saddle portion of a curb box and to align a valve stem of a valve supported at the mouths. The mouths are configured so as to permit universal utilization with a wide variety of valve configurations and sizes.
