Abstract
A labor saving system, method, and apparatus for connecting or coupling lengths of electric metallic tubing (“EMT”). The invention uses couplings/connectors that have barbs that are designed to engage corresponding indentations on EMT to ensure proper installation. In one aspect, the invention is an EMT having: an EMT inner surface forming an EMT cavity; an EMT outer surface; an EMT first end; and at least one indentation in the EMT outer surface at or near the EMT first end, the indentation adapted to receive a corresponding barb from a sleeve device. In another aspect, the invention is a sleeve device comprising; a sleeve inner surface forming a sleeve cavity adapted to receive an end of an EMT; a sleeve outer surface; a first sleeve end; at least one barb on the sleeve inner surface at or near the first sleeve end, the barb adapted to engage a corresponding indentation on the EMT.
