ABSTRACT:
A drain grate for installation within a concrete deck, along a periphery of the deck and below a base frame structure of a screen enclosure for draining water from the deck surface includes an elongate channel having a top plate with an exposed upper face, a bottom plate, and side walls extending between the top and bottom plates to define an interior fluid passageway therebetween. The top plate is provided with drain openings at close spaced intervals therealong and a rear side wall includes elongate drain slots permitting fluid flow from the interior passage to an exterior of the channel. When installed, the upper face of the channel is flush with the deck surface so that water accumulating on the deck surface is directed through the drain openings and into the interior passage of the drain grate from which it exits at the elongate drain slots on the rear wall and on to the grass or ground surface beyond the screen enclosure and deck.
