🚫 Seal out rats, seal in peace of mind!
The MF3 Rat Barrier is a 4-inch non-return valve designed for plastic or salt-glazed clay pipes that prevents rats from entering your drainage system. It installs easily into the exit pipe from your home to the street sewer, allowing waste to flow out while closing immediately after to block backflow and vermin. Made from high-grade plastic with an option for stainless steel, it offers a practical, durable solution to protect your property from pest intrusion through drains.
