Review on 🔧 Morris Type 21795 Knockout Screw by Jose Schweigert

I ordered a 4" knockout seal. On arrival it proved suitable for caulking a 4" hole and was even stamped 4". Due to my application I had to paint the seal prior to installation so there are no returns for me. I removed the old 4" plastic knockout gasket (also marked 4") and attempted to fit a Morris gasket. hmm? Something is not right! It won't fit in a 4" hole because the damn thing is actually 4 1/2" wide. I do not recommend this product unless you are looking for sharpness.
