Rat Blockers are designed to stop rats travelling 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 Blockers 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 Blockers 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. Both designs can be fitted from ground level, using a specially-designed installation pole. Source One Environmental supply two designs of rat blockers and both are available to buy online: Ratwall by Metex and TX11 by Nordisk.
