Escutcheon (furniture) An escutcheon (pronounced /ÉªËskÊtÊÉn/, i-SKUCH-Én) is a general term for a decorative plate used to conceal a functioning, non-architectural item. Escutcheon is an old French word derived from the Latin word scutum, meaning a shield. Escutcheons are most often used in conjunction with mechanical, electrical, and plumbing components and fixtures where a pipe, tube, or conduit passes through a wall [or other material] surface.
The coat of arms on an escutcheon forms the central element of the full heraldic achievement which consists of shield, supporters, crest, and motto. The design is a symbol unique to an individual person, and to his family, corporation, or state.
