It's really simple to assemble all this goes through the top count just know and follow the assembly order, you must initially roughing the gap setting the meter then close up the screws without blocking abatant is snap vertically in the lugs is immediately removed and then hangs bottom lugs having found their final place and replace the abatant. And more, it is comfortable, quiet, do not move. I'll see what happens over time, but for now it's nickel so I highly recommend it. I had purchased the optional stainless steel mounting kit.
