Determining the Height
Determine the screw height using the following formula.
H
screw height
=100 mm – d

100
mm: the minimum desired distance between the ceiling and the top of the equipment
when the column is fully extended.
 d = Hceiling - HMax = Hceiling - 2306 mm (Example height: The height of the
equipment without Base)
Ex) If
H
ceiling
is 2200 mm, H
screw height
value is calculated as follows:
d = H
ceiling
- H
Max
= 2200 mm - 2306 mm = -106 mm
H
screw height
= 100 mm - d = 100 mm + 106 mm = 206 mm
(If d is more than 100 mm, the column height limit is not necessary.)
d = 136
H
ceiling = 2,200
H
Max
= 2,306
H
screw height
= 206
