Adjusting the STAC - “Safety Torque Adjustable Clamp”
STAC 4 structure:
4a Quick release handle
4b Clamp insert side
4c Clamp limiter
4d Clamping force adjustment nut
 Make initial adjustment of the STAC clamping force by rotating the STAC nut 4d clockwise (to increase
clamping force) or counter clockwise (to decrease clamping force)
 Insert clamp, through 4b side, to the pole wider diameter side, until it reaches its limiter 4c
 Hold STAC with one hand (to keep it from rotating around the pole) while closing its quick release
handle with your other hand.
 If you feel that you need to apply too much force to close the handle, fully open the handle, slightly
rotate (counter clockwise) the clamp nut 4d and
try again to close it again.
 If you feel that you need to apply very light force
to close the handle, fully open the handle, slightly
rotate (clockwise) the clamp nut 4d and try again
to close it.
 Clamp nut 4d controls the clamping force of the
STAC. Higher clamping force is required for
aggressive maneuvers and will require higher
force to close the quick release handle
 After closing the quick release handle, try to
rotate the connected poles one relative to the
other. If they move by applying relatively light
force with your hands, it indicates that clamping
force is not strong enough and should be adjusted
as explained above.
Note: When locking the STAC onto one pole (without
the second matching pole), be sure to adjust the clamp nut for a light clamping force. Use a larger amount of
clamping force only when clamping 2 poles together.
