## Description

Contractor grade &#x2013; these are functional, not decorative. Can be painted for a more decorative look. Help prevent drafty floors and save energy by replacing damaged or missing foundation vent covers. May help prevent broken pipes by keeping your crawl space warmer - but this is not guaranteed. Our eco-friendly replacements, stamped from heavy-duty upcycled steel, are a quick and long-lasting solution. X-pattern embossed for strength. Tough to prevent rodent chewing and help to cover old rodent holes (see photos). USA-made from galvanized sheet metal scrap that might otherwise have gone into the landfill. Minor surface flaws, scratches and mfg marks are normal due to the material and mfg process. Can be trimmed to size or to fit around drain pipes using metal-cutting shears (not included). Each foundation cover includes a 1/4&quot; wingnut for installation on most homes with bolt in middle of foundation vent hole. 21.25&#x2DD; x 5.25&quot; standard size. Smaller size vent covers also available. Installation Instructions: CAUTION: Sharp edges. Wear gloves when handling. Some familiarity with using a drill and metal shears is recommended in case modifications are necessary. For most homes: Most vents openings have a 1/4-20 bolt protruding near the center. Simply slide the new vent cover over that bolt and then screw on the new wing nut. 1/4&quot; center hole can be re-drilled larger, if needed. Includes 1/4-20 wingnut which fits the original bolt on most foundation holes. Other wingnut sizes are available through your local hardware store. Vent cover can be trimmed to size or to fit around drain pipes. Use metal-cutting shears (not included). Can be painted to match home&apos;s exterior trim. We recommend painting before installing. For best results, install in winter and then remove and store in summer to allow ventilation under your floors.
