### ⭐⭐⭐⭐⭐ Knockout Seal Does the Job
*by M***H on March 3, 2025*

The meter base at a house on the Oregon coast corroded enough that a knockout seal came out. Once I had cleaned up the opening, I had a 3 and one-half inch hole to cover. The PUD would only accept a knockout seal and one that big is hard to find. But here it is! For a reasonable price and arrived in a few days. I installed it yesterday and it fit perfectly. In short, it worked exactly as advertised.

### ⭐⭐⭐⭐⭐ Exactly as described
*by A***N on May 26, 2025*

Exactly as described. Works great. Quick service saved my sale.

### ⭐⭐⭐⭐⭐ Great transaction!

Item as described and arrived on time...good to go!
