ST-132 CRANK STAND
PRODUCT DESCRIPTION
Thank you for choosing an ST-132 light stand from Global Truss
America. This stand has been designed to have a low loading
height, obtained by a multi-mast configuration. The telescopic
masts are made of treated steel and have been sized in order to
obtain maximum rigidity. The top mast has been designed with a
1-3/8” diameter steel tube which is standard in the industry for lifting
and supporting pro audio speaker cabinets. Special attention has
been placed on security. The spring loaded safety pins guarantee
extra security when operating the stand. As a third safety device,
each mast can be secured with a tension knob.
The ST-132 is equipped and shipped with:
A: Adjustable metal tripod base with telescoping leg
B: Large tension knobs
