I had two near me. The first one was already built and merchandise on it. I rearranged to match the planogram. The second one was not assembled. It was time consuming and the screws of one of the D Handles did not match with the holes. Anything with an Allen wrench took time as it was difficult to hand tighten. Bad machining.
I'd call the location before applying find out if the display has been assembled.
Do not read so much, look about you and think of what you see there.
