Update: After being contacted by the Chinese manufacturer asking for my address so they could ship me a part that would get to me in 3+ weeks, I purchased a more heavy duty rail that had a perfect alignment. Unfortunately, this didnt work either because the drawers are so wobbly on the cabinet, it put a lot of side to side stress on the rails. Please do not buy this product if you intend to use it as it is intended and sold.
Initial review: This was difficult to assemble, and Ive actually remodeled homes. It worked fine, but I was concerned about how long it might last. Sure enough, less than a year and the slide on the upper shelf came loose and the bearings went all over the place. Do not consider this if you want to use the entire capacity for files.
Poor product
