Threaded mechanical joint wall sleeve

Abstract

A threaded mechanical joint wall sleeve comprising a cylindrical member having opposite ends with inside and outside surfaces. The cylindrical member is adapted to be centrally positioned relative to a wall member and has an annular collar extending outwardly therefrom which is imbedded in the wall member. A pair of flanged end members or adapters are threadably secured to the outside or inside surfaces of the opposite ends of the cylindrical member and are adapted for attachment to the opposite sides of the wall member. A wide variety of wall thicknesses and pipe diameters may be accommodated due to the fact that the length of the cylindrical member may be varied and due to the fact that the adapters may be either threadably secured to the external threads or the internal threads provided on the opposite ends of the cylindrical member.
