I had the replace the plug clean out in my basement because I had to destroy it to get it out. The old one was a screw in and was completely flush with the floor. The new one sticks 1/4†above the floor surface but does not interfere with door which has to open above it. I like the flush screw head and the fact that it’ll be easy to remove if I ever need to in the future. It came with 3 Allen head wrench which was a bit of an overkill, but not a problem. It seals well and is built sturdy.

Product was a perfect replacement for the broken cap on my old cast-iron cleanout pipe. It was very easy to install.

Sizes aren’t correct but they work well. Had to get 3.5†for 4†pipe

This plug fits perfect in 4"cast iron pipe.

This plug fit perfectly. I’ve been having issues finding a plug for a 4†pipe. I finally measured the inside diameter of the pipe and looked for plugs accordingly. This was the only flush mount one that I found that would fit. It comes with everything you need for the install.

Buyer beware—I ordered 2 neither of them had the “provided Allen wrench†if it was a normal size, I wouldn’t mind at all BUT it’s not, it’s a giant size.

Not the heaviest duty cover, but will work for the side of my driveway. Installed it with zero difficulty. Make sure you read the specifications carefully, which I did before buying. This says 3.5" diameter, but it fits my 4" internal diameter pipe perfectly and it tightens up no problem (i.e., it is tight when installed and tightened with the included hex wrench). I spent hours researching the correct cover to install over this sewer cleanout pipe. Lived in the house for 8 years before I figured out the hole in the driveway was connected to the sanitary sewer (cleanout connection), after it cost $500 to remove the plastic cup that some yo-yo put in the hole years ago as a cover, which caused the line to become totally blocked.

Needed to cap off a floor drain in my basement, that occasionally let water IN and not out. So I got this flush-mount cap and all is well. Problem solved, no more water backing up from a slow utility sink drain.

Came without the key to tighten it, but I had a spare one that fits so it's all good. Is a good strong product.

The plug is just fine for use in a tube, but I needed it to seal a 1/8" plastic wall. Without a clear picture or a cross section drawing, it wasn't certain that it would work. Of course, it didn't work, the rubber seal is too far from the flange. But Amazon gets 5 stars for no questions return/refund. In it's place, I bought "Oatey 33403 Plastic Plug (with Galvanized Screw and Wing nut), 4-Inch" and that product worked perfectly (the rubber seal is directly against the flange).
