ABSTRACT:
Over a threaded plug closed cast metal fitting body joinable to a pipe stub end and at its top periphery bearing an integral single-turn roll male thread, there is telescoped and adjustably supported a housing assembly including a cylindrical plastic housing member, and a metal rim secured on the housing member top end providing a seat for a sealable access cover; the housing member interior over its full height having three integral pilaster-like formations each with a like series of sloped transverse grooves successively offset and spaced and shaped to provide an interrupted female thread engageable with the body male thread, so that by assembly rotation the rim is easily adjustable to be flush with an environment finish surface, for example, of poured concrete in which the fitting is embedded; thereby conducing to ease of installation as well as material, tooling and machine time fabrication costs.
