SKU KF61p0LN5
Designed to replace manual foundation vents, this automatic foundation vent fits standard 8 X 16 in. openings, ideal for ventilating crawl spaces. It operates without electricity, with a bi-metal coil that automatically opens at approximately 70°F and closes at around 40°F, responding to temperature changes. This functionality helps save energy by maintaining proper airflow and reduces the risk of frozen pipes. Additionally, it prevents foundation decay by effectively ventilating the space, ensuring a healthier environment. With 57 square inches of net free ventilating area, it delivers efficient air circulation. Constructed with high-density polyethylene, corrosion-free metal parts, and heavy-duty aluminum, it offers durability. Equipped with a stainless steel compression spring and adjustable screws, installation is straightforward, requiring no special tools. Simply knock out the old vent, remove mortar if needed to create the 8 X 16 in. opening, place the vent in position, and tighten the screws to secure it.
