13. Place linkage against the sash; mark an
approximate location to trim the excess linkage.
NOTE: When trimming off excess linkage,
make sure there is enough fork to fit
through the actuator. See Figure 14
(p. 7) and Figure 15 (p. 7).
14. Using the linkage-forming tool, cut the linkage at
location. Bend the linkage back and forth until it
breaks.
15. Clean the mounting area with an alcohol
towelette and allow drying.
16. Attach the linkage to the actuator car by
inserting it through the holes on the side of the
actuator car. See Figure 15 (p. 7).
17. Remove the protective paper from the adhesive
backing on the mounting plate.
18. Close the sash; move the actuator and linkage
to your estimated mounting position.
19. Lightly press the mounting plate onto the sash.
NOTE: Make sure that the plate is mounted
so that the sash can travel without
running the actuator block off the
track or interfering with any
obstacles.
20. Adjust the mounting plate if necessary and firmly
attach the mounting plate to the sash.
Attaching Linkages to Sash Panels
NOTE: If applied without pressure to the mounting
surface, then you may remove and reapply
the linkage if necessary. If pressure is
applied, then the adhesive is permanent.
1. For best performance and appearance, mount
the linkage squarely and uniformly on the sash
panel. Also, use the palms of your hands and
press the mounting blocks and decorator plates
firmly on the sash glass.

• For horizontal: To determine the linkage
mounting block location, hold the free end of
the linkage flat against the sash panel.
As a general rule, the linkage should be
mounted toward the inside edge of the sash
panel. However, for two-sash configurations
it is recommended that the linkage blocks be
mounted on the center of the sashes (Figure
24).

Figure 24. Linkage Mounting Block Locations
(Two and Four sash configurations).
• For vertical: Generally, the linkage should
be mounted approximately 1 inch from the
inside edge of the sash panel. See Figure 9
(p. 6).
To secure linkage to the vertical sash frame
use a 3/16-inch sheet metal screw.
• For combination: Make sure that the block
is mounted so that the sash can travel
without running the actuator block off the
track or interfering with any obstacles.
2. For linkage blocks mounted inside of the
fume hood and on the glass. Align a decorator
plate (that is the same size as the mounting
block) on the front of the sash glass. Clean the
decorator plate mounting area with the alcohol
towelette. Peel the protective backing from the
decorator plate. Line up the edges of the
decorator plate with the edges of the linkage.
Press the plate firmly to the sash glass.
