ABSTRACT:
An overhead door bracket for attachment of the main arm of an overhead door opener to a metal overhead door for the purpose of opening and closing the door. The inventive bracket has a relatively wide mounting plate which spans the distance between the portions of the sheet metal doors having existing reinforcing backing strips for mounting of the hinges connecting the metal panels of the door. The inventive bracket has conventional connecting tabs spaced and extending outward to receive the lower end of the main arm of an opening system. The tabs have pin receiver bores for pivotally securing the main arm to the bracket by means of a pin. The bracket mounting plate has three spaced rows of mounting holes for mounting the bracket to the upper panel of a hinged door panel, the mounting holes being proximate the respective ends of the bracket.
