The rain gutter is conventional in construction and is elongated having an open top formed by two spaced apart and parallel upper edges. The outer upper edge of the gutter includes a lip. The device includes an elongated screen having a pair of spaced apart edges. One edge is designed to engage the outer rain gutter lip so that, with the other edge of the screen in engagement with the building facia board, the screen is compressively retained to the rain gutter so that the screen overlies and covers the open top of the rain gutter. In order to facilitate the attachment and detachment of the screen with respect to the rain gutter, an elongated V-shaped depression is formed longitudinally along the screen. This V-shaped depression forms facing wall sections of the screen which, when compressed together, retract one or both of the screen edges from the rain gutter thereby facilitating both attachment and detachment of the screen.Field of SearchCOVER WITH SURFACE WATER RECEIVER AT EAVE OR VALLEYWith separator; e.g., strainer Inwardly of edge With downspout Between oppositely sloping sections With additional subsurface liquid receiver Grated inlet surface drain Flat grating at surface level At upper edge of filtrate receiver Resting on internal stop or surface Screens, e.g., woven | |
