Ratwall is a cost effective and robust stainless steel Rat Blocker that is ideal for installation into underground drains. Ratwall can be installed by hand or from street level and has a unique low force fit. Ratwall is suitable for plastic, clay and cast iron drains. Ratwall has a unique external hinge allowing maximum waste flow. The external hinge block ensures that the unit cannot become dislodged and lost into the sewer pipe.
Usage:Ratwall installation instructions
Ratwall installation is easiest to install from street level using the optional installation pole. Ratwall has a unique feature that ensures a low force installation by holding the Ratwall unit in compression until it is in place within the pipe. For full details download and follow the installation instructions. All Rat Blockers should be inspected and maintained according to the installation instructions.
Installation without the installation pole
Ratwall may be installed using the supplied nut and a 17mm spanner in place of the installation pole. This gives the installer the benefit of holding the unit in compression for a low force installation.
Installation into chamber inlet – orientation of flap
Ratwall is factory configured to work within a manhole chamber outlet, but can be re-configured to protect a chamber inlet. For full details download and follow the installation instructions.
Fitting a Rat Blocker from Metex will prevent rats accessing the building through the protected drains. However, a Rat Blocker alone may not guarantee the removal of rats already in the property. We recommend consulting a professional Pest Controller to ensure the correct measures are taken to ensure all rats are removed and cannot return.
