Abstract: A cleanout extension adaptor for insertion into a cleanout extension construction in a plumbing arrangement. The cleanout extension adaptor includes a cylindrical body with a small, thin lip on the top for seating on the top of a cleanout extension. The cleanout extension adaptor has internal threads which accommodate a threaded plug that is contained within the confines of the cleanout extension when installed. The cleanout extension adaptor permits cutting the cleanout extension so that it is even with the surrounding surface. When the plug is inserted into the cleanout extension adaptor, the cleanout extension and plug are substantially even with the surrounding surface. This avoids cutting out or altering the surrounding surface in any way.

Abstract: A cover for covering closure plugs and openings and the like comprises a generally circular plate with axially positioned and extending latching fingers for engaging the corners of intersecting walls of a tool cross slot upon rotation of the cover for releasably retaining the cover in place over the plug.
