Hello, I design this gutter filter cap / anti rodent, to keep wild animals from entering my drain pipe.
The diameter is 50mm and there is an offset space where you can add some silicone paste for better adhesion. This cap is installed on wall where drain pipe end open.
Hope you like this one and don't forget to send me a comment for improvement.
Enjoy...Cheers
