The Happy Drains rat blocker is 100mm (4 inches) diameter and suitable for clay, PVC & cast-iron pipework.
Secured into the pipework within drainage chambers, it effectively stops rats and rodents from entering a property via the drainage system.
The special design features two curved stainless steel toothed one-way doors. With no restriction of flow within the pipe, it is easily fitted by mechanical compression within the pipe and installed from ground level.
