Product Details: Rat-Proof Flap OUT 4 Inch Vented

Rat-Proof Flap OUT 4 Inch Vented is a patented stainless-steel flap designed to help deter rats from entering through drains. It is used inside compatible non-return valves to add rodent resistance where a standard plastic flap may be vulnerable to wear or gnawing over time. The stainless-steel design provides a tougher barrier while maintaining the valve’s intended function.
