PARTS INCLUDED
1. If holes are not
drilled in panels,
pre-drill 7/16" in
diameter holes at
least 1 3/8" deep,
1 1/4" from edges
as shown. Tap pivots
into holes with light
hammer blows as
shown.
2. Trim track to fit
finished opening
length if necessary.
3. Secure the track to
the head jamb with
the provided
#8 x 1" pan head
screws through the
pre-drilled holes.
4. Position the lower
bracket in the jamb,
centered with the
track, and secure
with the provided
#8 x 3/4" flat head
screws.
5. Place the upper pivot
pin into the hole in
the top pivot bracket
and the guide pin
into the track. Lift
the assembly and
place the lower pivot
pin into the lower
bracket. If installing
a four door system,
repeat for the other
assembly. Check
positioning and
operation.
Two and four panel
assemblies should have 1/4" clearance between the pivot doors and
each jamb. Four panel assemblies should be snug at the middle.
Door panels should be folded to gain access to the adjustment screws.
In some cases, the doors may need to be removed to properly access the
adjustment screws.
To adjust horizontally:
6. 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. Retighten.
7. At the bottom,
loosen the
adjustment screw
and move toward or
away from the jamb
until doors are plumb
with jamb, then
retighten the screw.
To adjust vertically:
8. Lift assembly slightly
and rotate the
adjustment screw
flange to the right
to raise doors, and
to the left to lower
them.
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.
