Definitely seems professional restaurant grade. Super strong and smooth to turn, even when fully loaded with cast iron pots. No step by step installation instructions, but figured it out. A major improvement to our dead spaces. We have multiple corner cabinets in our kitchen and bought one of these to see how we liked it. Loved it so much the first day, that we just installed a second one in the other corner. Seems like they will probably outlast the cabinet they are mounted in.
