    Patent number: 7950188
    Abstract: A gutter protector formed of a flexible open cell porous foam has at least one undulated bottom surface. The undulations of the bottom surface may be ridges defining generally parallel channels to direct water through the gutter passageway. Optionally, undulations may be provided on one side surface. Such undulations on the side surface may be ridges or other convolute cut projections that are compressible and help to secure the gutter protector under compression within the gutter passageway.
