Boat and RV owners, listen up! This 4-inch circular inspection hatch is exactly what you need for easy access to those hard-to-reach areas. Made from super durable ABS plastic that can handle sun, saltwater, and heavy foot traffic without cracking or fading. The non-slip surface with its square pattern gives you solid footing while looking seriously professional. What we really love is the excellent sealing - the built-in rubber gasket and threaded design keep water and dust out, so your storage stays dry. Installation is a breeze with the detachable cover and included stainless steel screws. It opens 180 degrees and can be mounted vertically or horizontally wherever you need access. Perfect for boats, yachts, RVs, campers - anywhere you need a reliable inspection port. The inner diameter is 4 inches with a 5.5-inch outer diameter, and you'll need to cut a 4.4-inch hole. Pro tip: Use some silicone sealant around the edges for extra waterproofing. This hatch is built to last and makes maintenance so much easier - definitely a smart upgrade for any marine or mobile application!
