ABSTRACT:
A snow brake has three major portions, all of which are formed together in a single mold by casting. The first part is a gripper base having a rectangular U-shaped cross-section and an elongated side elevation. A slit extends upward from a bottom of the base to receive a roof seam. Set screw openings extend inward from one side wall and to the slit. Indentations are formed in the side opposite the set screw openings, so that the set screws may press portions of the seam into pockets formed by the indentations, deforming the seam and locking the base to the seam of a standing seam metal roof. The snow retainer is a curved plate which is inclined to the base at about a 60.degree. angle. The plate is wide at the curved bottom and is curved inward toward the top. Thick side walls of the base provide rigidity of the entire structure and use the force of the blade for preventing separation of the sides of the base when forcing the set screws inward to deflect the seam into the indentations to anchor the base on a roof seam.
