One of the most significant reasons for employing rat blockers is to protect the health and hygiene of occupants within properties. Rodents can carry diseases and bacteria, posing health risks to humans. By keeping them out of drainage systems, rat blockers help mitigate these health concerns. Rat blockers require no previous installation experience and require no long-term maintenance once installed. It can be installed at either the pipe's entrance or exit, and the included bolt can be adjusted to match the flow direction. ## Features - ✔ DOUBLE NON-RETURN FLAP PROTECTION: Features twin stainless steel non-return valves that allow free wastewater flow while helping prevent rats and rodents from entering through the drain.
