Abstract
An adjustable support piece is provided which can selectively raise or lower the level of a building surface or industrial component such as a mechanical pump, etc. A base member, crown member, and threaded tubular stem which can be cut with a hand saw are provided and which can be selectively adjusted in height to raise or lower the height of the building surface. In one embodiment, a coupling may be used to interconnect two tubular stems together. Further, a crown coupling spacer may be used to moderately increase the total length of the adjustable support piece.
