Review on Oatey 42373 Brass Cleanout 2 Inch by Russell Robertson

I was hesitant to order this product because I wasn't sure the product description provided an accurate measurement of the product. It turned out that my intuition was correct. Although the product is stated to be 3.5 inches, it looks more like 4 inches and does not fit in the intended cleaning plug. A little disappointed and I've learned my lesson. Don't buy products that actually need to be measured prior to purchase.
