Extremely well build product, easy to install.
I have 2 dogs and didn't want to replace my beautiful patio door. This was the perfect alternative.
5 years ago, I purchased a Thermo Sash 3 small pet door from you folks. I just wanted to send a quick note to say that, while some products become a disappointment over time as they age and wear out, your product continues to be great quality. Thanks for a great product!
