1. Position the guide, 
upper pivot pin and 
lower pivot pin on 
the door assembly 
in the locations and 
orientations shown. 
2. Measure in 5/8" 
from the end of 
each panel and 
center each pin on 
thepanel.
3. Secure with a 1" at 
head screw through 
each hole.
4. Position overhead 
track in the opening 
with the open 
side down and the 
bracket end toward 
the jamb. Allow 3/4" 
between the front 
of the opening and 
the track and drive 
the 1-1/4" pan head 
screws through the 
pre-drilled holes 
until snug. Position 
the lower bracket 
on the oor in line 
with overhead track. 
Fasten to the jamb 
with a 1¼" at head 
screw through only 
the middle of the top 
slotted hole.
5. Unlock the track pivot latch by pulling the latch away from the jamb. 
With the door assembly folded, place the guide in the track and then 
position the upper 
pivot pin next to the 
track pivot. Slide the 
pin away from the 
jamb into the track 
pivot. Slide the latch 
toward the jamb to 
lock the pivot pin in 
place. Verify the pin 
issecure.
6. On the bottom, 
depress the arm on 
the lower bracket 
and insert the 
lower pivot pin. If 
installing a four door 
system, repeat for 
the other assembly. 
Check positioning 
andoperation.
To adjust horizontally:
7. At the top, loosen 
the screw in the 
top pivot bracket 
and move toward 
or away from the 
jamb until there 
is 1/4" clearance. 
Re-tighten. Repeat 
the process for the 
lowerbracket.
To adjust vertically:
8. There should be a 
slight gap between 
the lower pin and 
the bracket. If there 
is no gap or the 
gap is too large 
and allows the pin 
to come out of the 
bracket, loosen the 
single screw in the 
bracket and adjust 
up or down until 
there is a small gap 
and the pin is engaged in the bracket. When the bracket is properly 
adjusted, install the remaining two screws and tighten.
9. Loosen the screw on the snugger and close doors. Move the snugger 
until it contacts the guide pin. Open doors and move the snugger an 
additional 1/8" toward doors and tighten screw. Doors should slightly 
“snap” shut, but reopen easily with a tug on the knob.
