Review: Awesome - Fits well and saved my house from squirrels entering my attic
Review: Good Quality Replacement Part - This is a good quality replacement part. The top width is slightly bigger than the 3-3/16 inch drain grate that it replaced. But that's on me for not measuring before ordering. This part is as described and will still work for my application.

### ⭐⭐⭐⭐⭐ Awesome
*by R***I on December 17, 2025*

Fits well and saved my house from squirrels entering my attic

### ⭐⭐⭐⭐⭐ Good Quality Replacement Part
*by W***S on January 1, 2026*

This is a good quality replacement part. The top width is slightly bigger than the 3-3/16 inch drain grate that it replaced. But that's on me for not measuring before ordering. This part is as described and will still work for my application.

### ⭐⭐⭐⭐⭐ It dosen't seem like a lot, but is the rain floods your back yard, it is a big deal.
*by J***D on May 15, 2024*

I don't know anything about outside plumbing but when it rained the placement of my backyard French drain caused debris to make it worthless, I went to my GOTO source, Amazon. I saw this black, rugged drain cape at a great price. It arrived the next day and I installed it in less than a minute. It is a better solution than I had before and with some drainage work, I think I will be good when it rains. As of this writing, I am waiting for the rain.
