Abstract

Pieces of thermal insulating molded rubber are configured to conform to under-sink piping, so as to provide protection against burn injury from contact with hot surfaces. The pieces are telescopically and interengaged with one another at selected relative orientations, to cooperatively enclose a P-trap assembly, and the piece covering the J-bend is formed with a protrusion to accommodate clean-out structure provided thereon.
