This is the most common hot tub heater element on the market used by Balboa & Correct-tech. All elements are factory tested.
I was not sure but this element fit perfectly in my water heater...
Great price and received it quickly and was easy to install.
Reconnected everything and was extremely pleased to have a working spa again.
Nice to know that when parts break down there is a part source to get you back up and running like new!
