Measurements are provided in the pictures to make sure I did them correctly. I measured the "width" at 3/4 of an inch, "height" at slightly over 1 inch and 1/8th, and the width of the single steel ball bearing wheel is 1 and 1/4 inch.
Is it possible to upgrade my rollers to double wheels and will that help for a more smooth and sturdy modification?
Any help is greatly appreciated, thank you for your expertise.
