Features:

Easily applied by snapping on to end of either anvil or spindle, thus permitting two attachments to be used together
Balls are hardened, measure .200" and 5 mm in diameter, and move freely in the retainer, insuring positive contact with anvil and spindle
The diameters, .200" or 5 mm, of each ball used must be subtracted from the micrometer reading
