### ⭐⭐⭐⭐⭐ Great for odd ball sizes
*by  on Reviewed in the United States November 25, 2025*

I needed to plug two old floor drains, and after multiple trips to many big box stores, I found these. They work great and when I need to open them, they are easy to use. Very happy with my purchase.

### ⭐⭐⭐⭐⭐ The Perfect Cleanout Plug!
*by  on Reviewed in the United States May 30, 2025*

Must have cleanout sewer plug! Attached image is the 4" lead cap i had previously used. Needless to say, the lead cap rubber would get warped when hammering the cap off to clean out trap and sewer smell leak out. I searched diligently online for replacement cap and stumbled upon this cap. I ordered oatey 4" plug which ironically did not fit. Apparently the 4" pipe is not exactly 4 inches. The fact that this plug fits 3.9"+ is fantastic. Manually tightening it is a plus as well. Cleanup will be a breeze moving forward and the rubber will be easier to clean when removing the plug to clean out my trap. Highly recommend and worth the money.

### ⭐⭐⭐⭐ Good fit
*by  on Reviewed in the United States October 11, 2025*

The size was just right — it fit my pool plug perfectly and sealed up without any issues. It seems to be made of decent materials and looks well-built at first glance. However, I’m not fully sure about the durability yet. I’ll have to see if it actually holds up over the winter. So far, it works fine, but time will tell how long it lasts.
