Questions about this item

What does the 51/64 inch size mean when the stud cleaner is mounted on a tool?

The cleaner is specified for use with 49cx81 through 49cx87, indicating a direct fit for those Chicago Pneumatic tool models.

What physical clearance is needed to install the 2-3/8 inch long cleaner?

The 2-3/8 inch length requires that much axial space on the stud, and the plastic and steel construction fits standard chuck openings.
