We bought this as a stopper for a 1939 fish pond we restored. Although the drain measured at 1.5 inches, it needed about a 1.75 " stopper . Plus, it was not perfectly round, so any solid plastic solution left a void on the not-round side. After trying a couple other similar, but rigid expansion plugs, we tried this and it worked perfectly. It was small enough to fit into the hole, but it also expanded enough to make watertight contact with the wonky sides. So, not quite the purpose this was designed for, but it absolutely worked.I had the same issue as others with that center screw spinning around, but after a certain point I just cranked it down as much as possible then banged it on in with a rubber mallet. It hasn't leaked yet!

Ordered these plugs for our pool. The came quickly but were to small. Quality of the plugs were great but unfortunately we couldn’t use and it wasn’t because of the company it was our fault. We did however give them to our neighbors and they have used them and they have worked out great.

I bought this to plug an unused 2" washing machine drain pipe that started evaporating and letting gasses into the house. It works great for this purpose. It seems plenty durable and is able to expand quite a bit.As others have noted, it's tricky to tighten the wing nut because the bolt in the center just spins freely, though this is only a problem until you get it a little bit tight. To get it tight in the first place, I used channel locks to compress the plug, which made it very easy.

This plug is for the in ground pool. The last plug I had 25 years plus. I am familiar with the performance and quality. I didn't hesitate to replace with the same quality product.
