The 331 Type pedestal stands are ideal for permanent
installations requiring excellent stability and a short, adjustable height instrument
stand. This stand has a working height range from a minimum of
24" (61 cm) to a maximum of
37" (94 cm), not including
any adapters which may be mounted on
top of the intermediate tube.
This height measurement is taken from the floor to the top of
the intermediate tube, on which all instrument mount
accessories are attached. Custom heights are
easily manufactured.
A variety of stand adapters, slides, lifts, and various instrument mounts
fit into the intermediate tube. Refer to the chart below
for the various stock options, or request your own variation.
The stand has an air cushion damper to prevent the column from "free
falling" and damaging the instrument in the event that
the collar lock, ratchet pawl, and lift handle are released at the same
time.
The baseplate is a 1" thick steel plate with a diameter of
15-1/8" (38.4cm). Four 1-1/16" (2.7cm) mounting holes
are equally spaced on an 11" (27.9cm) diameter on this baseplate.
It is also outfitted with four 5/8" x 11 UNC-2B threaded leveling
screws to provide a means for adjustment to set the stand vertical. |

Finish: Machine grey; other finishes available on request. |
