Ratwall stainless steel drain barrier suitable for installing within either outlet or inlet of both 100mm clay or 110mm PVC drainage pipe. Secured into pipework within drainage chambers, effectively stopping rats and rodents from entering a property via a drainage system. Ratwall can open fully with no hinge within pipe diameter, allowing maximum flow. Device shape ensures it cannot become dislodged and lost in drainage line. Rats cannot pass the Rat Flap device against the flow.

It is easily fitted by mechanical compression of the side walls allowing the unit to be installed by hand in a shallow chamber or if required an optional installation pole is available separately in ‘you may also like’ below. There is no silicone or securing cable required for installation. Full installation details and chamber warning label are included within the box.
