until they both are slightly above

must be done to prevent the screws 

from scratching the base while

3. Move the base up or down to desired 

height (1” increments) and align set 

screws to adjustment holes in the 

base. Using a

tighten the second set screw into the 

base adjustment hole, to just below 

flush with the column. The first set 

screw will draw tighter from this 

process. Ensure that both set screws 

maintain equal depths (Figure 2 & 

Detail B). 

5. Carefully turn the desk to the upright 

position. 

Note: 

Adjustable leveling glides 

are supplied on Ruckus desking.
