452B Starrett Cylinder Gage 2-1/2-6* Range

452B
Starrett Cylinder Gage
2-1/2–6"

These convenient, easy-to-use gages are
used to determine taper and out-of-roundness
of bores, offering a quick and accurate way
to show your customer whether new rings or
reconditioning is necessary.
The ranges are achieved by the use of two
measuring contact rods. The gage is easily
and accurately set to a micrometer.

Features:

• Dial is graduated to show plus or minus
• Bezel may be rotated for zero setting
• Sled is hardened and ground for long,
  accurate life and has two long-line
  contacts in constant alignment with the
  cylinder wall. These reference points are
  spring loaded, making the gage self-
  centering and non-collapsible
• The locking screw (stem protruding
  above the dial) clamps the contact points
  in position for measurement with a
  micrometer
• The handle can be locked in any
  perpendicular or angular position and
  may also be transformed by a slight turn
  into a toggle joint with a wide sweep
• Extra handles may be ordered to make a
  long extension
