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 adjustable short radius members extend from the track radius members to guide uppermost rollers of an overhead sectional door. The overhead door system includes a pair of stationary sheaves positioned outboard of a pair of horizontal support rails which support the horizontal track members. A detent is provided at one end of the adjustable radius members to prevent undesirable travel the garage door. A spacer is provided for use in extension spring configurations when a long horizontal support rail is required. The spacer prevents metal-to-metal contact of moveable sheaves with the horizontal support rails.
