It's always satisfying to communicate exactly what you need to your mechanic, refrigerator repair person, doctor, etc. Your knowledge is a key ingredient to get the correct product or best service.

For the next three weeks, we are going to discuss finding the right wheel or caster. I will walk you through steps to consider, and I'll share some insider tips. We want to make your caster purchase as easy as possible.

Let's first start with the wheel.

" I need a wheel"

Have something in mind or are you replacing one? We will begin with finding a replacement, since that is a little easier.

To us, there's nothing more important than making sure our replacement fits in the same spot as your existing one. Do not assume there is a "standard" -- our industry makes thousands of different wheels. Initially, we want measurements more than type of wheel or what is it doing. So, get your wheel and give us the following specs when you call or e-mail:

• Diameter of wheel
  • This is the distance vertically from one end of tread to the other.
• Width of tread on wheel

• Hub length (One of the most important measurements)
  • This is the distance through the center of the wheel.
• Bore/ axle size
  • It is sometimes easier to measure the hole in the wheel than the diameter of the axle.
  • If you have both handy, double check yourself.
  • Usually the axle is smaller in diameter than bore. This is because it has to pass through the center.

Now you are ready to shop! Use our website to see if there's an exact match there. If not, don't hesitate to call or e-mail us. Keep those measurements handy!
