This was a simple fix with no tools required. These pivots simply snap into place to hold the row into place so classes will stand securely in place in your dishwasher. If you need the larger space they can be removed. Like I said a simple fix but if you are unsure this shop has a short video for every part they sell and shows you how so you have the opportunity to watch as many times as necessary. Reasonable prices, rapid delivery & we will order from them again if the need arises! Thanks a million!!
