Rat Flaps are designed to stop rats from traveling through drains and are installed into pipes within inspection chambers (manholes).
 

They are usually installed into the drain outlet, but these models can be easily configured to be fitted into a drain inlet.
 

Rat Flaps allow rats to pass freely downstream but protect property by preventing their movement upstream. By installing a Rat Blocker into the drain outlet, all upstream branches are protected.
 

Rat Flaps are robust stainless steel devices and are held securely in place with a tight friction fit. Due to their design, these unique Rat Blockers cannot become dislodged into the drainage line.
