Steel Rat Blocker prevents rats from entering buildings through the drainage outlet. The non-return valve allows free flow of waste but blocks any rodents attempting entry in the other direction.
You can stop calling your pest control and solve the problem once and for all.
The 4 inch rat blocker is an ideal solution to block rats from entering your property permanently. Our 4 inch rat blocker is made from non-corrosive stainless steel and we offer a 12 month warranty.
