Abstract
Abstract The invention disclosed herein relates to plumbing fittings and particularly to means for extending the length of stems thereon which might be necessitated because of the inaccuracy of mounting the valve body with which the stem is associated interiorly of the wall so that the same does not extend outwardly for enough therefrom to permit the installation and mounting of the usual escutcheon and handle on such stem. It is contemplated that the extension may be provided in any particular length desired and in various lengths where required to accommodate for the positioning of the valve body from which the main stem to be extended protrudes for the purposes set forth.
