Method of connecting sections of metal conduits

A method for connecting sections of metal conduits extending on opposite sides of a concrete floor in a multi-story building, the floor being formed by pouring concrete over a form, the method comprising the steps of:

• positioning a first section of metal conduit on form with a first open end against the form and a second open end extending at least about one inch above a desired height of concrete to be poured over the form;
• installing a removable ring about the first open end of the first conduit section abutting the form for creating an open space circumscribing said first end after pouring of the concrete;
• positioning a relatively rigid cover over said second end of the conduit section, the cover having an aperture extending therethrough;
• inserting a releasable fastener through the aperture in the cover and into the form;
• tightening the fastener to compress and hold the conduit section in a fixed position on the form;
• pouring the concrete onto the form and hardening the concrete in situ about the first conduit section;
• removing the fastener and form to expose the first end of the conduit section;
• removing the ring from about the first end of the first conduit section to expose a selected extent of the first end;
• and
• coupling second and third sections of metal conduit to respective first and second exposed ends of the first section of conduit.
