Review: Seems to work - Positives; it’s well made, hinge design is good in that it is largely external to the pipe when fitted so doesn’t reduce its bore, and the nut tightening mechanism to fit it works well. Sizeable metal ‘stop’ prevents loss down the sewer if it comes loose. Negative; CHECK YOUR INSPECTION CHAMBER before ordering- I discovered that the inflows and outflow pipes all had significant overhangs of the brick walls above them ,which meant I couldn’t use the fitting rod from the surface to place the rat wall. Fortunately a bucket of caustic soda/water mix poured over the inside of the chamber carefully and then a rinse off with a hose made getting down there to place the rat wall and manually adjust the nut a lot less unpleasant!
Review: Works well and good material/manufacture - Easy to fit but care needed that the drain is a straight piece otherwise may be difficult for a corner

## 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.

A: Yes

A: You just need to turn the flap around for an outlet

**Q: My drainage pipes are 100mm (just over 4 inches).  Will this fit?  It's advertised at: 110mm/4" so I assume so but 110mm is closer to 4.3".**
A: Hi I run a drainage firm and can confirm these will fit your 4" drain system. The 110mm advertised size is the outside diameter. I have fitted 4 of these now and they work well.
