Like the quality and look of this door but would caution you on installing it at the height they tell you. The slit in the bottom lf the door is not deep enough to fit the guide in it if you mount it at the height they recommend.  I did not relize that was the issue at first as all i knew is my door would not sit on the rail correctly. I ended up shaving off part of the bottom of the door before relizing it. Ended up removing the guide from the midde of the door and placing it infront of the door to keep it from swinging out. I do not like how the bottom looks now. I will have to sand and try to repaint it.
