653G Dial Comparator Stand with Granite Base without Indicator

653G
Starrett Dial Comparator Stand
with granite base

These bench-type comparator gages are ruggedly built for in-process
and final inspection work.
The dial indicator can be adjusted vertically and locked in any position.
A sliding ring with locking screw below the beam permits swinging the
indicator to either side. The ring also acts as a safety device, preventing
the beam from accidentally dropping. There is a fine adjustment on the
beam for final indicator setting.
The hand lifting lever on the indicator raises the spindle and releases it
to contact the work. Left hand lever furnished unless otherwise specified.
Both gages have a maximum vertical capacity of 9-1/4″ (235mm) and
a throat depth of 5″ (125mm) and a vertical indicator fine adjustment
of up to 1/2″ (12.7mm). Post diameter is 1-1/2″.
653 Series has a precision ground cast iron base measuring
approximately 8″ x 9″ (200 x 225mm).
653G Series have a Starrett Grade A, Crystal Pink ® Granite base,
measuring 8″ x 12″ x 2″ (200 x 300 x 50mm). Base is finished
