I bought the dishwasher adjuster/positioner because one was missing from the upper rack on the machine in the house we moved into. When it arrived from Appliance Parts Pro, I followed the video to replace it. However, in removing the Upper Rack Adjuster to replace the dishwater adjuster/positioner I broke the Upper Rack Adjuster (plastic gets brittle after use inside the dishwasher after time). So, I had to order another Upper Rack Adjuster. I was careful on the install on the new Upper Rack Adjuster and did not break it. All's well now and the upper rack slides in and out as it's supposed to.
