1. An electrical box extender comprising:
- an adapting member having an outward side and an inward side and having a flange substantially perpendicular to the adapting member and extending in the direction of the outward side of the adapting member;
said flange having an inward side and an outward side;
said flange bordering an aperture of said adapting member and oriented substantially about a principal axis of extension of said adapting member;
an extending member, having an inner surface and an outer surface the extending member oriented about the principal axis of extension of said adapting member and in close proximity to the inward side of said flange wherein the extending member has at least one protrusion extending from the outer wall contacting the inward side of the flange, the at least one protrusion oriented parallel with the principal axis of extesion;
at least one adaptor fastener mounting plate having an aperture for receiving a fastener with an aperture, the at least one adaptor fastener mounting plate extending from an edge of the adapting member ending in a direction toward the inward side of said flange and beneath said flange;
each of the at least one adaptor fastener mounting plates having an associated extender fastener mounting plate for receiving a fastener, each extender fastener mounting plate fixedly attached to the extending member and having an aperture;
each extender fastener mounting plate aperture substantially aligned with the associated adaptor fastener mounting plate aperture;
at least one fastener for detachably attaching said adapting member to said extending member by way of the aligned adaptor fastener mounting plate aperture and the extending fastening mounting plate aperture;
whereby travel of the extending member maintains mechanical and electrical connectivity between the extending member and the adapting member while modifying the height of the extending member reletive to the adapting member in an adjustable and substantially reversible fashion.

Abstract
Disclosed is an electrical box extension that includes an extending member for switch and/or plug mounting having one or more fastening brackets, one or more base fastening brackets and one or more fasteners that together with optional contact points provide for mechanical and electrical connectivity between the extending member and its associated electrical box and provide sufficient mechanical resistance to support the adjustable elevation of the elevating member thereby supporting a flush surface for surface mounted sockets, switches and their associated plates.
