ABSTRACT:
An elongated body member is of inverted U-shape and is capable of seating in a gutter over a downspout opening. The body member has cross slots and bottom edge notches in an arrangement that efficiently stops leaves and debris but that allows water to drain through. Further, the body member has tapered end portions terminating in rounded tip ends that also are engaged by leaves and debris for efficient straining. The construction of the body member allows the sides to be squeezed together for fitting into eave troughs and the like during installation.
