Abstract: A terminal mounting track for supporting objects of more than one type has a base which is designed to attach the track to a support surface. A support member projects from the base and an elongated mounting rail is supported by the support member in a spaced apart relationship with the base. The rail has a pair of spaced apart elongated mounting flanges and a mid-portion which joins the flanges to the support member. The mid-portion includes a first wall segment and a second wall segment which are joined together so as to define a V-shaped groove which is configured to accept a sheet metal screw. Objects such as other dimensions of rails and electrical boxes may be mounted to the track using a sheet metal screw that engages the groove.
