The Ratflap provides a permanent, simple, cheap solution to the worldwide problem of rats in sewers. This device prevents rats from moving from the main sewer into the pipes servicing your property. The Ratflap will stop these rats from breaking out of a damaged pipe underground avoiding the need to dig the pipe up to find the problem, which may have given them access to your building or surrounding property.
The Ratflap can be quickly and easily installed and can be installed in either the upstream or downstream pipe thanks to the reversible flap.
The Ratflap is available in 4″ (100mm) and 6″ (150mm), other sizes available upon request.
