About this item
- SMOOTH EDGE, NO SPIKE DESIGN FOR BETTER FLOW: Unlike traditional serrated rat blockers, our smooth edge no spike design helps reduce the risk of debris build-up and drain blockages while still effectively preventing rodents from entering through sewer pipes. Allows smoother wastewater flow for reliable everyday drainage performance.
- EFFECTIVE DOUBLE FLAP RODENT PROTECTION: Features a heavy-duty double flap non-return valve system that blocks rats and pests from travelling back through drainage pipes into your property. Engineered to maintain uninterrupted water flow while providing dependable anti-rodent protection.
- STAINLESS STEEL CONSTRUCTION: Manufactured from high-quality stainless steel for superior durability in underground drain environments. Corrosion resistant, rust resistant and gnaw resistant for long-lasting protection in domestic and commercial drainage systems.
- FITS STANDARD 4 INCH CLAY & PLASTIC PIPES: Designed for compatibility with standard 4-inch sewer and drain outlets including clay and plastic pipe systems. Ideal for homes, restaurants, warehouses, offices, commercial buildings and industrial drainage applications.
- COMPLETE INSTALLATION KIT INCLUDED: Supplied with 1 x smooth edge rat blocker valve, nuts and bolts set, securing cable and nail, plus installation instructions for easy fitting. A cost-effective alternative to traps and poisons, backed by a 12-month manufacturer warranty.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
