This vintage nautical cowl vent is made of steel and stands about 25 3/4 inches tall. The mostly circular mouth of the vent measures 10 1/4 x 10 inches. The mounting flange measures about 7 1/2 inches in diameter and has six mount holes. Our vintage nautical cowl vent weighs 6.6 pounds and has a weathered look after being used on a real vessel. Some of the silver paint has worn off and there’s a few small dents here and there.
