ABSTRACT:
An improved guard for guttering having a U-shaped clip for holding the guard in rotational contact with the front flanged edge of the gutter is disclosed. The guard is comprised of a screen member attached to the front edge of the gutter and extending across the gutter mouth to the leading edge of the roof. The U-shaped clip is equipped with two rotational nodes, wherein the first node is located on the gutter flange so that the screen rotates into contact with the leading edge of the roof, and the second node is located directly to the rear of the first node on the outer edge of the gutter flange so that the screen can rotate as much as 135.degree. from full closed position over the gutter to a fully open position substantially perpendicular to the ground. The screen is comprised of intersecting cross members which intersect with the line of the leading edge of the roof at angles of from about 10.degree. to about 80.degree. and about 170.degree. to about 100.degree., respectively, wherein said members are inclined or declined with respect to the plane formed by the front flanged edge of the gutter and the leading edge of the roof.
