## Description

Metex - Ratwall For 110mm/4" Pipe. Made From Robust, Corrosion Resistant Stainless Steel With A One Way Valve & Flap. This Rat Blocker For Drains Is Easy To Install By Hand Or At Street Level

## 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.
- ONE-WAY FLAP PREVENTION: The Metex Ratwall 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.
- EASY TO INSTALL PROTECTION: This Rat Blocker compresses and expands for easy, frictionless installation and a secure fit. Can be installed by hand or from street level with a separately available installation pole. Suitable for domestic use in plastic, clay and cast iron drains. Features an external hinge that enables maximum waste flow.
- RATWALL RAT BLOCKER: This listing is for a 4" / 110mm version. The rat wall can be installed into 100mm Victorian drains. Instructions are included, and we also offer a support video to help with installation. We also have installation instructions for with or without an installation pole. A 6" / 150mm variant is also available.
- METEX: We specialise in non-toxic rodent control equipment including our Nordisk and Ratwall rat valves as well as RatTape proofing tape. We are a UK business that designs and manufactures innovative products for construction professionals and the DIY market, working with manufacturers both in the UK and overseas.
