We're excited to introduce the latest addition to the RatGate range: the 4” Liner RatGate, specifically developed for drainage pipes that have been lined.
The new device offers the same effective rodent prevention as our standard 4” RatGate, but with a slightly smaller diameter to accommodate pipes where lining has reduced the internal space available.
Why Have We Developed a Liner RatGate?
Lining is a common method of repairing damaged drainage pipes without needing to excavate and replace entire sections of pipe.
However, installing a liner reduces the internal diameter of the pipe, which can make fitting a standard RatGate device difficult or impossible.
Our standard 4” RatGate is designed for pipes with an internal diameter of 100mm. The new 4” Liner RatGate is designed for pipes with a reduced internal diameter of 95mm, allowing effective rodent prevention in suitable lined drainage systems.
