ABSTRACT:
The present invention relates to a novel strut and bracket apparatus for mounting to a section of an overhead garage door, the strut and bracket combination being utilized to selectively impart the desired tensile forces to the section, thereby correcting or otherwise compensating for any misalignment or tendency for misalignment in the section. Specially shaped brackets are used along with hardened steel bolts to assure secure and safe attachment of the strut to the bracket.
