Fits perfect, seems sturdy
Fits perfect, seems sturdy. Make sure you measure circumference and divide by two, don't just measure lenght/width.

Looks good and protects
While the cover is not a perfect fit for my backflow preventer it still fits and looks very nice. It keeps the brass staying nice looking and helps keep the warmth in when the temperature gets low. It is very easy to install, and it covers the entire backflow preventer. It has been outside for almost 2 years and has held up very good. It is thick and is definitely worth the money to save your backflow preventer from corrosion and the element elements.

Cold weather
Easy to use, very good quality and cheaper than changing my pipes after a freeze.

Fit Perfectly.
I bought two as I have an upside down "U Shaped" piping. I put one on each side. Good fit. Easy to put on and take off with Velcro.

Great product
Covered part of the pump equipment for our pool when we were going to have a freeze. It worked perfectly and protected our pool equipment.

Great fit and price - it works
Fits incredibly well over my irrigation system pressure breaker. Very happy with it and paid about half of what I would have at an orange big box store for a bag that was way too big.
