3.
Place a four foot level on the top frame and secure the second fastener in the top frame at
the other corner, ensuring the top frame is level.
4.
Finish attaching the top frame by securing
one screw at each stud, 16" to 24" apart,
depending on the type of construction.
➤
Space screws no more than 30" apart if
mounting into the header.
5.
Secure the pivot side frame, using a level to
make sure the frame piece is plumb. Again,
use shims as needed.
➤
If there are two pivot sides (split stack),
secure only
one
of the side frames.
Step C. Attach the Aluminum Track to the Frame
1.
Before attaching the track, make sure that you have inserted the correct number of carriers
and top pivot pins. For one-way operation, one pivot pin and one snubber are required. For
split operation, two pivot pins are required, but no snubber.
IMPORTANT:
Carriers have three wheels. It
makes no difference whether they are loaded
into the track with one wheel to the front or
two wheels to the front.
2.
After inserting the carriers, check that the carrier
heights are the same as the pivot pin height, as
shown below. Adjust as necessary.
