IPS 83688 3-Inch Flush Mechanical Cleanout Repair Plug

New basement apartment in older house. Has some kind of drain/maintenance hole in the middle of the floor of one of the rooms. Crappy maintenance guys had plugged it with a normal 3 inch cleanout plug I assume in order to prevent backflow from the sewage system during rain. Only problem with the standard version of these plugs is that they have a large bolt that sticks up a good 2 inches from the floor and make for an incredibly dangerous foot impaling, tripping hazard, toe breaking, death trap. Absolutely not meant for this purpose, and dangerous. This product solved that problem wonderfully. It sits mostly flush, and is a good low key color. The fitting was tight, but this was not being fitted directly into a pipe. It was slightly larger than the original 3inch plug that had been installed, but it did fit. I would caution against trying to use this for 3 inch pipe directly as I believe it is designed for the flared part of pipe fittings, not the pipe itself. TLDR: For my unique and very specific use case, this was a perfect product. Can not vouch for other uses.

Perfect for Broken threads or flush mount cleanout. Fits inside of Female adapter. No trip Hazards here.

Good price but none functional. This measure 3.25" but says 3". Did not fit my 3" pipe.

The unit would have been great but the concrete around the drain would not allow the plug to seat properly. Like the idea that it is flush but didn’t work based on my existing conditions

An old brass cover on the driveway kept falling through the hole whenever a car drove over it. The hole was larger than 3 3/8 inches. This fit well and could be tightened so it doesn’t move. No problems with car tires. Very happy result.

This is advertised as a 3" plug. Actual measurements are 3.2" min and expands to 3.65" max as you tighten with the enclosed allen wrench. Appears to work fine for my 3.5" ID drain pipe. Don't use this if you have an actual 3" ID pipe. It won't fit in.

NOTE!!!!! The minimum OD of this plug is 3.20" - It will not fit into a pipe that is 3.00" ID. Otherwise, nice quality part.

Perfect fit just what I needed

Read the reviews and noted that the size was not as listed, but it is a perfect fit for a 3 inch fitting with 3.5 inch inside diameter. The plug without expansion is approximately 3.25 inches and will expand to more than 3.5 inches.

Excellent product
