Has anyone fitted castor wheels on the bottom of an american fridge freezer?

[cba]

We have a huge amercian fridge freezer which we have moved out of the kitchen as we are getting a new floor fitted.

Has anyone fitted castor wheels onto the bottom. It would be alot easier if on wheels to change the water filter on the back. I dont want to scratch my new floor pulling it and out.

If you have where did you get them from?
