It is an excellent product! I love it, I am quite a handy woman so I knew some calculations would be required. I noticed the width of these only come in one size, but not to worry, the metal frames that come with it will keep it sturdy once drilled in. I only drilled into my framed cabinet on one side away from the door. Luckily, you can drill the metal frames into the back and bottom to make it work. I did not have to drill on the frame where the door is. 
It slides out beautifully with no issues.
