Crawl Space Doors can also be painted with a plastic adherent paint! Crawl Space Doors are designed for encapsulation and crawlspace access. Most foundation doors are either rusting or rotting and detract from the "curb appeal" of your home; not to mention attracting termites, rodents, and other pests. Our Crawl Space Doors are made from a durable and attractive ABS/UV treated plastic that will not rust or rot. You simply mount the frame over the foundation opening with the included hardware, place the cover over the frame, and secure with the included pins. It's that easy. All models come with a 3" frame for mounting. For example, if your foundation opening is 20"x32", you would want to order this door, allowing an extra 3" for mounting. Total Dimensions=26"x38".
