Abstract A gusset for fastening the corners of hollow frame doors, in a manner so as to prevent opening of the miter joint, comprising a generally right triangular base plate having peripherally upstanding flanges terminating substantially at right angles to the base plate and extending along the angularly related sides and the hypotenuse, each side flange including an end portion extending lineally beyond the hypotenuse and both ends of the hypotenuse flange being provided with extending flanges which are contoured angularly to overlie the extended side flange portions, when the gusset is inserted in place within the door, fasteners extending through the top and side rails of the door engage in the respective extending hypotenuse portions to draw the miter joint tight.
A corner gusset for joining two angularly related corners of hollow frame doors having cooperating channel shaped rails comprising, a base plate having a substantially flat body section of generally triangular configuration having two right angularly related sides and a hypotenuse to lie with the channel shaped rails, the marginal edges of the angularly related sides and the hypotenuse being flanged laterally substantially at right angles to the flat body section to form rigidifying flanges terminating substantially at right angles to the plane of the flat body section, the terminal ends of the rigidifying flange on the hypotenuse being contoured angularly at obtuse angles to align at its opposite ends with the rigidifying flanges of the angularly related sides, and means defining aligned apertures in the obtusely angled ends of the hypotenuse flange and aligned portions of the rigidifying flanges of the angularly related sides.
