Hatch Screen, Lewmar 20-3/16" x 20-3/16"

Part #: Z3666
$80.87
This screen is of a different construction than the original aluminum framed screen which is no longer available. The perimeter of this screen is a rigid rod concentric with the shape of the frame. A fabric surround covers the rod and secures the screen to the rod. The screen assembly is held to the underside of the hatch using your existing rotating tabs that are attached to the hatch trim.
A pair of special plastic hinges are included with the screen. By replacing a pair of the tabs, the screen can now be hinged open temporarily to gain access to the dogs or adjust how far open the hatch is during the night.
