Hello Lenny, thanks for reaching out. I went out to our warehouse and measured the Caliber 3" Spool Roller # CA52AJ. The overall width is of course 3". The diameter at the widest part is 2-3/4". The diameter at the middle is about 2". It fits a 1/2" shaft. I edited a picture for you to help illustrate.
