Received the 48" wide Gladiator EZ Connect Rack Shelf shipped to my door via FedEx, and once all of the necessary parts and instructions were moved to our garage, assembly took only about 20 minutes. It was easy to put together and the instructions were quite clear. Once assembled, my garage went from a cluttered mess to an organized workspace in about an hour. Plenty of room for everything on this unit. Seems very sturdy and should last for years to come. Far better than any plastic shelves I've had in the past.
