Abstract: The present invention relates to a novel torsion spring apparatus and method wherein anchor loops are formed in the end coil of the torsion spring to permit anchoring the spring directly to the appropriate mounting bracket. The provision of anchor loops in the end coil of the torsion spring effectively eliminates the requirement for conventional mounting inserts for the torsion spring and simultaneously increases the effective length of the torsion spring or, alternatively, permits the torsion spring to be shortened by the number of coils that would be otherwise rendered ineffective by the presence of a prior art insert.

Abstract: An end stile apparatus and method for an overhead door section. The end stile is formed from a rectangle of sheet metal folded longitudinally into a modified J configuration in cross section. Mounting elements in the form of tabs and clips are prepared from a side of the end stile and serve as part of the anchoring system for mounting a panel to the end stile.

Abstract: A novel overhead door section system and method, the section including a section facing fabricated from a high tensile steel and secured to a novel end stile and center stile. The end stile includes an angle support secured therein. The angle support clamps an end of the section facing against a front face of the end stile and is secured to ribs in the section facing and to a side wall of the end stile. A novel back facing and method provide additional strength to the panel and may also enclose an insulative layer inside the panel.
