Starrett Flex-O-Post Indicator Holder with magnetic base

For use with all Starrett Test, Back-Plunger, AGD, Dial, and Miniature
Dial Indicators . Also accommodates similar indicators of other
manufacturers . The flexible post is an assembly of short tubular steel
sections and precision ball joints, linked by an internal steel cable . It
can be adjusted to any position and locked by turning a lever near the
magnetic base . This makes it possible to use indicators in awkward
places that are hard to reach with conventional holding devices .
Assembled to the magnetic base, the post has a vertical reach of
approximately 15" (380mm) and a horizontal reach of approximately
10" (250mm) . The indicator snug on the end of the post can be rotated
through 360º and locked in any position .
The base has three precision ground magnetic contact surfaces . Grips
horizontally, vertically or upside down . V-step holds base to arbors,
shafts, chucks .
The 657W Attachment allows fine adjustments to be made, operated
by turning the fine-adjusting thumb screw (with post locked in rigid
position) to zero, then set the indicator .
