Description
The 4″ Rat Barrier is a robust, rodent-prevention device designed to stop rats from entering buildings through 100mm (4-inch) drainage pipes. Installed directly into the pipework, it acts as a one-way non-return valve, allowing wastewater to pass out while preventing rodents from moving upstream into properties. Ideal for homes, commercial buildings and drainage networks.
