This product is fantastic. We needed a 6’x6’ gate at the side of our house. It was so easy to attach this frame to the side of our house. 
The frame is expandable and is made of very sturdy metal. It allows you to attach your choice of wood, so if you’re not handy, have your wood cut at your lumber store. Very easy to attach the wood to the frame. We’ve had this gate for over a year and it continues to work really well.
