It was much taller than I expected. I didn't think ahead about it being for the entire height of the cabinet. I had a drawer small drawer above it that I had to remove in order for it to fit. Great product. It had a weird thing about a third slide screwed to the bottom of it which made no sense to me because it has to be screwed in from underneath, so its kinda useless. The instructions are really useless and vague... Good rating because the quality of product is good, with high quality metal glides.
