SANTA ANA, Calif. — Everyone likes to take pride in their ability to put something together. It’s human nature. However, some coin laundry owners have missed the mark when it comes to laundry carts, according to R&B Wire Products.After seeing a variety of its carts in various facility settings featured in American Coin-Op, the company noticed that some of the carts (58-100 series, 56-200 series and 55-300 series) have the crossbars of the double pole racks installed upside down. If installed improperly, hangers can slip off the rack.The company offers some installation advice. When installing the crossbar, make sure that the brackets are facing upward — allowing the crossbar to be installed below the side poles. When installed properly there will be 1 1/2 inches of the side poles extending above the crossbar. The two carts shown illustrate the different installations. The cart on the right has the proper installation.
