Perfect fit
Capping off an abandoned well and was actually harder than expected to find a cap to fit. This one is great quality and fits exactly.

Super useful
Had a 4” cast iron clean out with a really jagged top. This plug is nice and deep, so it sealed it up perfectly. High quality, really happy with it

Fail
I tried to plug a couple of floor drains that always back up during severe thunderstorms. Well last night we had a big rain and the floor drains backed up onto the basement floor like when there wasn't any sort of plug. The plugs didn't seem to do anything to stop water flow. For one I hand tightened the wing nut. For the other I used a socket wrench to tighten a nut so I think they were as tight as could be reasonably expected.

Wing nut broke on first time use. Wrong dimensions on website
As some other reviews noted, wing nut broke on first time use. Also the dimensions for 5" and 6" are swapped on website.
