Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a brief look at this replacement RV toilet floor flange. This is going to replace the floor flange for your RV toilet. The three-inch female NPT end threads into your RV's blackwater system. You are going to have 0.541 inches of usable female threads.
And then let me pull out my ruler here just to confirm some other measurements with you. You're gonna have a four-inch diameter opening that's going to hold your toilet wax ring. The overall diameter of this is gonna be seven inches. And the hole cutouts for securing the flange to the floor and to the toilet to the flange are pre-drilled. And the diameter from those hole cuts on one side to the hole cuts on the other side, we're sitting right at about 5 1/2 inches.
Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..
