Review on Black Valterra T05-0782 4x3 inches 1.88 inches Male Threaded Floor Flange by Todd Phillips

Out of stock at Big Box stores. If you want this part you will look everywhere to find it. I assume they were commonly used on RVs decades ago. It has a 3" male thread and is made of hard plastic. Perfect for replacing the one I took off to fix the toilet. The slots are positioned correctly to replace the brass studs that hold the toilet in place. I used one Piece of wood and a hammer to screw it firmly onto the existing vertical drain pipe by tapping the notches clockwise. There are eight holes to securely attach the plastic base to the floor. I had to use a simple wax ring [not a plastic extension]. to complete the work.Works great, no leakage.
