Abstract
Height-adjustable fixtures for buried tubulars and methods of adjusting the height-adjustable fixtures. The height-adjustable fixtures include a frame and a plurality of slot nuts. The frame has an upper frame surface, a lower frame surface, a flange that defines a plurality of slots, and a central opening that extends between the upper frame surface and the lower frame surface. The central opening is sized to provide access to a buried tubular conduit of the buried tubular. Each slot nut is shaped to be received within a corresponding slot. In some examples, each slot nut defines a lower nut surface, an upper nut surface, and a neck region positioned between the lower nut surface and the upper nut surface. In some examples, when each slot nut is received within the corresponding slot, the lower nut surface is recessed within the corresponding slot.
