## Description

Nordisk 150mm Rat Blocker. Made From Marine Grade Acid Resistant Stainless Steel With A One Way Valve & Two Serrated Flaps For Double Protection. Easy To Install Industrial Rat Valve.

## Features

- STOP RATS TRAVELLING THROUGH DRAINS: One of the primary ingress points for rats into a domestic or commercial property is via the drainage system, either directly from the main sewers or a collapse within the pipe. A Rat blocker is installed within the inspection chamber to stop rats movement upstream. By installing a Rat Blocker all upstream branches are protected.
- DOUBLE PROTECTION: The Metex Ratwall has two sharp serrated flaps for double protection from rat infestations. This also allows liquids and solid waste to pass down the system whilst preventing access to rats moving upstream. The rats cannot pass or chew through the barrier flap, thus preventing their access to re-infest. All models of the Nordisk TX11 Rat Blocker are supplied with reversible flaps so that the same unit can be used in either inlet or outlet pipes.
- WRC & VA APPROVED: The only UK rat blocker to achieve Water Research Centre Approval, the benchmark in UK water industry. The Nordisk rat blocker has also passed the stringent VA Approval issued by the Danish certification body, ETA-Denmark, and inspected by the Danish Technological Institute.
- PROVEN PROFESSIONAL RAT BLOCKER: Over 250K units installed worldwide, this rat flap is proven in professional pest control use over 10 years and used in 1 in 6 Danish homes. All parts of the rat valve are made of marine grade 316 acid-resistant stainless steel for demanding environments. Unique patented design with expanding sides allows the rat valve to slide into the drain without friction. Easy to adjust for drain inlet or outlet positions
- METEX: We specialise in non-toxic rodent control equipment including our Nordisk and Ratwall rat valves as well as RatTape proofing tape.
