Are the top rack wheels in your dishwasher broken?
The wheels that make your dishwasher rack roll are designed poorly. The hubs are plastic, but they're assembled with a sheet metal screw at the factory. That means they're probably broken before you even do your first load of dishes.
Unfortunately, you can't just buy a new part. You have to buy an entirely new rack.
We make an indestructible replacement kit of custom hubs, machine screws, and lock-washers.
The kit is made entirely from commercial food service high grade 300 series stainless steel that never cracks or rusts. They operate smoothly, and the temperature extremes of your washer won't affect them.
Now, you don't need to throw out the largest part of your dishwasher just because of one little broken piece.
