458 CANADA IMPROVED SERVICE COLUMN AND METHIOD OF MANUFACTURE ABSTRACT OF THE DISCLOSURE . An elongated electrical service column is formed from two longitudinal outer members made from sheet metal cold rolled steel and which are inclusive of a protective zinc coating or other protective coating, painted and finished as desired. These are inventory stock items which are cut to length. The sheet metal column sections include two confronting longitudinal edges which are bent inwardly to form co-acting surfaces for mechanical connection. An internal member inclusive of longitudinal grooves, and also formed of cold rolled steel, forms an internal barrier and is also cut to length. These members are then snap-fitted together, with the complementary edges of the longitudinal outer members force fitted within the longitudinal grooves of the internal barrier. The finished column is then at- tached at its upper end to a T-bar forming a part of the ceiling and the lower end is fitted with an anti-skid section which is engageable with the floor.
