Abstract
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.
