The Tools You Will Need
• #1 Phillips screwdriver • athead screwdriver • tape 
measure • small nail • 3/32” drill bit for pilot holes
• hacksaw or ne tooth saw (needed to trim top track)
• safety glasses • ne sandpaper (used to smooth 
edges after trimming).
SINGLE DOOR INSTALLATION
1. Measure the Door Opening
36” x 80” door: The nished opening of 
your doorway should be a maximum of 
36” wide and 80” high.
48” x 80” door: The nished opening of 
your doorway should be a maximum of 
48” wide and 80” high.
The Express One Plus door height 
cannot be altered or trimmed.
2. Install the Top Track
Cut the top track 1/8” shorter 
than the width of the opening. 
Position the top track on the 
top of the door opening so that 
it is straight and centered.
After making a pilot hole 
(with a nail or a 3/32” drill bit), drive a 1” track screw 
through the screw hole nearest the center of the track. 
Do not tighten. (Tape may be used to hold the track in 
place while you mark and drill.)
4. Install the Door Panels
Apply track lubricant to each top glide. Swing 
one end of the overhead track out of the door 
opening to accept the top glides. Decide if you 
want the door to 
open from the left 
or the right, then 
slide all top glides 
onto the track. 
Stack the panels 
together near the 
center screw.
5. Secure the Top Track
Swing the track back to 
its original position. After 
making screw pilot holes 
(with a nail or a 3/32” 
drill), drive the 1” track 
screws through all track 
holes. Set all screws as 
straight and tight as 
possible to assure 
smooth operation of the door.
6. Secure the Anchor Panel
Use the closure
channel to measure 
and align the channel 
clips. Align the 
channel on the 
non-opening side
of the door jamb. 
Make sure the 
channel is plumb.
Mark each of the ve
closure channel screw
holes and remove the
closure channel. Make
pilot holes (with a nail 
or a 3/32” drill bit) and install the channel clips 
loosely, using ve of the 1” roundhead screws. 
Align the clips vertically and fully secure the 
screws. Press the door anchor panel onto them 
until it snaps into place.
7. Secure the Closure Channel
Align the closure channel on 
the opening side of the door 
jamb. Make sure the channel 
is plumb. Mark each of the 
ve screw holes (as above).
If necessary, cut the channel
to match the door size. Make 
pilot holes in door jamb (with 
a nail or a 3/32” drill bit) and 
install the closure channel, 
using ve of the 1” 
athead screws.

Double Door Installation
1. Measure the Door Opening
36” x 80” Double doors: The nished opening of 
your doorway should be a maximum of 72” wide 
and 80” high.
48” x 80” Double doors: The nished opening of 
your doorway should be a maximum of 96” wide 
and 80” high.
The Express One Plus door height cannot be 
altered or trimmed.
Divide the width of the opening by two. Cut 
each overhead track to this measurement so 
that when installed, the tracks butt against one 
another in the center of the door opening. 
It is also acceptable to use one track if it will t 
your opening.
2. Install One Top Track
On a center line drawn across the top of the 
door opening, install either half track and install 
all screws in the half track. Refer to single door 
step. If using a single track, use one 
center screw. 
3. Install the Door Handles
Tap the two handle attachment pins into one 
handle, then t the pins through the door panel 
holes. Press the other handle onto the pins.
If necessary, you may back one handle with a 
solid object and tap the other handle alternately 
over each pin area until the handles are seated. 
Do not strike the middle of either handle.
Repeat with other handle.
4. Install the Door Panels
Apply track lubricant to each top glide. Install 
the two doors in the half track with lead edges 
facing each other. If necessary install the second 
track and push one door onto this track. Set a 
track screw at the track center joint and leave 
the screw projecting down 1/2” to prevent glides 
from passing the joint.
5. Secure the Anchor Panels
Use the closure channel to measure and align 
the channel clips. Align the channel on one of 
the door jambs. Make sure the top of the
channel is plumb. 
Mark each of the ve closure channel screws 
holes and remove the closure channel. Make 
pilot holes (with a nail or a 3/32 drill bit) and
install the channel clips loosely, using ve of the 
1” roundhead screws. Align the clips vertically 
and fully secure the screws. Press the door 
anchor panel onto them until it snaps into place. 
Repeat on the other side of the door jamb.
6. Install the Closure Channel
Align the closure channel on the lead edge of 
one door so that it is plumb with the top and 
bottom of the door. Mark each of the ve screw 
holes on the lead edge and drill ve pilot holes 
with a 3/32” bit. Secure the closure channel
using ve 1” athead screws.
