Robustly constructed, featuring a durable cast housing,
and designed for shop or laboratory use, the Spi gage
will provide years of reliable and accurate surface finish
assessment. The gage is also designed to take
measurements from a variety of positions and several
angles. It works on both horizontal ad vertical surfaces
and can even be used
upside down.
