Review on Jones Stephens Corporation T31004 Economy by Justin Zilinskas

I found a 4" pipe in the wall that was loose with a rubber stopper. Unfortunately the tube was pressed against the wall and the cap didn't fit properly at the back where there was no space between the tube and the wall. I bought it so it could clog the pipe without slipping over the pipe but so it slides inwards. The connector is well made and I was able to hand tighten the tube by tightening the wing nut. It's a good design and very durable. The rubber expands when the wing nut is tightened, but the plug was free to enter when the wing nut was loosened. This is a solid product and well made. My only concern would be that metal parts will rust if left in a humid or humid environment for a long period of time.
