The M-Series stands have been requested both by customers and
other metrology instrument OEMs. With their input, Brunson has designed
this instrument stand for functionality and portability. This
collapsible, tripod-type stand is available in a number of
standard configurations. Just tell us your preference:
Graphite or aluminum legs. These stands are
available with aluminum or graphite double upper legs, which
span from the shoulder pivots to the "knee" of the stand.
Stands with graphite upper legs have a lower weight and give
an advantage with respect to thermal stability.
Adjustable or fixed instrument mount. The stand is
available with either an adjustable instrument column, also called
the "intermediate tube" (below, left) or with an
instrument adapter fixed directly to the tribrach at the top
of the stand (below, right). The adjustable instrument mount employs a
handwheel-driven worm gear for up-and-down adjustment of the
instrument column. The collar may then be clamped to
avoid any inadvertent instrument movement. An adapter on
top of the intermediate tube provides a standard external 3½"
x 8 thread for mounting instruments or other adapters.
Note that the intermediate tubes on our M-Series portable
stands do not have the same internal threads as found on our bigger stands, and
as such will not directly accommodate adapters such as the model
800 precision lift.
The "fixed height" version of the stand has an adapter
mounted directly to the top of the stand. For applications where
fine vertical adjustment of the instrument is not necessary, this version
reduces cost and increases lateral stability.
Note that the height of either type of stand (fixed or adjustable
mount) may be adjusted by extending and locking the lower legs at
the desired position.
Short or Tall. The M-series
stands are available in a short or tall version. The
double upper leg section and the adjustable instrument column of the tall version
are longer, providing the additional height.
The lower leg sections are the same length on both versions.
Points or Pads. The stand's lower leg will accommodate
two different types of feet - trivet points (below, left) or
swivel pad-type feet (below, right). The swivel
pads have a thin, textured rubber pad on the bottom. (We know what
you're thinking - rubber? But it works fine.)
Either type of foot is an acceptable choice for general
applications. The points work well on uneven surfaces,
the pads work well on soft surfaces (ex., linoleum) which the points
may damage. Pads have the additional advantage of
being outfitted with a hole for semi-permanent mounting.
The feet are easily interchangeable in the field. The
M-Series comes standard with trivet point feet, and the pad
feet are available as an option.

Use the legend at left to construct the part number for the
M-Series stand that best suits your needs - or give us a
call, and we'll help you determine the best
configuration. Remember that the M-Series comes
with trivet point feet as standard, but the following
foot options are available:
For pad feet instead of trivet points, order part no. 9887-G2 (a
price differential will apply).
For both trivet points and pad feet, order part no. 9887-G1.
