Great Product - Exact Replacement for current cover with crack in it.
Pretty solid. Old cover got hit by a mower (previous owner) and tore a chunk out of it. New cover is exactly like the old one. has a gasket and screws to screw it down and seal against water. Would buy again.

Perfect fit/replacement cover. Came with 6 stainless steel screws and gasket seal as advertised. Also, this cover has a second model number other than "3009-RC 20". It's "PL-20RC" and can be seen in the picture.
