Question: I am looking to get a sliding shelf for use in a stereo cabinet for a turntable. Do the tabs on this shelf need to mount to the front of a cabinet or could it mount internally to the side walls of a wooden cabinet box?
Answer: Thank you for your inquiry. Unfortunately, looking at the dimensional drawings, it does not appear this shelf could be attached to the sidewalls of a cabinet without significant modifications.
