A frame for supporting a piece of equipment, particularly an air conditioning unit, onto the roof of a building is constructed using fastener means integral to the sheet metal so that the use of nuts, bolts or other fastening devices is eliminated. In particular, the fastening means comprise a slot cut into one piece of sheet metal and a dimple and tongue punched out of a second piece of sheet metal. The tongue is slipped into and over the slot until the dimple locks into the slot and thus holds the two pieces of sheet metal together.
