Wheel diameter size

I think I have 81-056 rollers for my sliding patio door. I?m getting ready to order new ones, however when I determine if I need a 1 inch or 1 1/4 inch diameter wheel, where would I measure? From the outside lip of the wheel or the inside concaved part? And will I have problems if I order the wrong wheel diameter? Thanks

Hi, thanks for posting. Even though there is an adjustable screw on the assembly, it would be better to match your wheels to the new assembly wheels that come with 81-056. Measure the outside diameter of your old wheels before ordering. Let us know how it goes.
