Our pipe shelves arrived quickly. (We were missing one section of pipe, but after contacting the vendor it was sent and arrived shortly after.) Love this new space and the look it added to our kitchen. And...I priced this out buying it in parts at our local box DIY store. Would have cost 4 TIMES as much, so great value through this vendor!The instructions are online as part of the ad.We connected them as instructed, but laid each section down on a table before adding the next section. This allows you to hold one area in place and push on the bar of the next section with the flange connected; this helps to line each bar up that is going to connect to the wall. We did this with towels underneath to make sure not to harm the table. We placed them on the wall where the studs are located to allow for screwing each flange into the stud. They are there to stay, super sturdy.Remember, they come without shelves but that worked out great for us because we wanted to match our cabinets.
