BOTTOM BRACKET FOR UPWARD ACTING DOOR

摘要

Bottom edge brackets for an upward acting door each include a base part including fastener receiving bores for securing the brackets to the bottom edge of the door, a flange projecting substantially normal to the base part including a connecting lug mounted for connection to a becket or loop of a door lifting cable and an integral rolled tubular guide roller support portion for supporting the shaft of a door guide roller. Each of the brackets also includes a hook portion projecting from the base part and adapted to be received in an opening formed in the bottom edge of the door for retaining the brackets connected to the door when door lifting forces are being applied thereto if one or more fasteners is loose or removed from the bracket.
