Schaefer Marine Plate/Flat f/Up To 1/2" Line Exit. Schaefer's stainless steel Schrader Exit Plates have a flat bottom which allows the escape of any water that may back-into the hull. An exit port with an O-ring trap will allow water to exit below the hull but only for a short distance then it needs to be pulled out of the way with a hose spigot or a small hose splice. Schaefer Exit Plates have a rust-resistant surface that will last for years on end. Plus these corrosion-resistant Exit Plates have a lifetime limited warranty.
