A method for connecting sections of metal conduits extending on opposite sides of a concrete floor in a multi-story building in which the floor is formed by pouring concrete over a form. The method comprises positioning a first section of metal conduit on the form with a first open end against the form and a second open end extending above a height of the concrete to be poured over the form. A removable ring is fitted about the first open end of the first conduit section abutting the form to create an open space circumscribing the first end after pouring of the concrete. A relatively rigid cover is positioned over the second end of the conduit section. A fastener is inserted through the cover and into the form and tightened to compress and hold the conduit section in a fixed position on the form. Concrete is poured onto the form and allowed to harden about the first conduit section. Afterward, the fastener and form are removed to expose the ends of the conduit section. The ring is removed from about the first end of the conduit section to expose the end such that other sections of metal conduit can be connected through the embedded conduit section.
