A universal overhead door system includes a pair of horizontal track members, a pair of vertical track members and a pair of track radius members interconnecting the horizontal and vertical track members. A pair of short radius members extend from the track radius members to guide uppermost rollers of an overhead sectional door. The short radius members terminate close to the top of the door opening and thereby eliminate the need to guide the uppermost rollers below the level at which the curved portion of the track radius members begin. The ability to install the short radius members when needed for smaller door opening sizes and low head room environments provides a universal track system for most overhead door installations.

Universal overhead door system

A connection system for interconnecting various components, such as components of an overhead garage door system, is provided which includes, in one aspect, a first component having a pair of spaced apart hook members, an intermediate guide member and a detent extending from a planar body of the first component. A second component includes a pair of spaced apart apertures which are shaped and aligned to receive the hook members, and an intermediate aperture which is shaped and aligned to receive the guide member upon registration of the first and second components in face-abutting relationship. As the first and second components are translated relative to each other, the detent of the first component engages the intermediate aperture of the second component to thereby establish a connection between the first and second components. Connection of a roller bracket to a door stile of an overhead garage door system is provided by the novel connection system, as well as connection of a door stile to a door panel. In a second aspect of the invention, interconnection of horizontal tracks, vertical tracks and track radiuses is provided by the novel connection system to form continuous door tracks on opposite sides of a door frame.
