These screens received high ratings from Practical Sailor, which judged the mesh small enough to prevent no-see-ums from getting through!
Installation is a cinch: just put them over the hatch and the generous dimensions allow it to open fully for maximum ventilation below. The bottom contains a lead ballast to keep screens in place on the deck - no cords, ropes, or straps needed. Also includes a heavy duty plastic case for easy stowage.
There are four convenient sizes to choose from - be sure to select a screen size that is at least 1 inch larger than your hatch all the way around.
