Would Not Recommend

The joining kit was suppose to work with the same series of windows. It did not. There were no instructions with the joining kit, I assume the maker thought whomever bought this would already know how to install it.

Bought this to build a bigger window. Actually bought 10. Perfect fit and did not add too much width.
