Installation Guide

STEP BY STEP INSTALLATION INSTRUCTIONS FOR BIFOLD DOORS
ROUGH OPENING FOR NEW CONSTRUCTION
The construction of the rough opening for single or double bifold doors should be designed so that the opening conforms to our
recommended finished opening dimensions. The finishing of the rough opening can be either a wood frame or drywall because the
bifold installation hardware that comes with the bifold can be surface-mounted to either material.
RECOMMENDED FINISHED OPENING DIMENSIONS
This chart allows for a 1/8” (3.2 mm) gap at the top of the bifold and a 1/4” (6.4 mm) space on the sides of the bifold, after it has been
installed. The installation hardware is adjustable so that you achieve these tolerances. It also allows for clearance over any
finished floor covering. Your bifold is purchased on the basis of a nominal size which is slightly larger than the actual size of the bifold.

How to Install your Bifold Doors:
Please read the complete instructions
carefully before you start installation.
All instructions apply to any size of folding
door installation. The same instructions
also apply to all types of door panels.
Cut track
If necessary, cut
track to 3 mm (1/8”)
less than the width of
the finished opening.
Use a fine tooth
hacksaw.
Install track
Ensure that the pivot bracket in the
track is at the side which you
prefer your doors to open toward.
Now, fasten the track along the center line
of the header, using screws provided.
Tap in pivots
Tap top pivots
and bottom
pivot into place.
Several light
taps directly on
top of the pivot
should seat it
properly.
Note: Universal pivots are also sold separately.
Install jamb bracket
Place jamb bracket, tight
to floor, so that center hole
of bracket is plumb with
hole in the top pivot bracket
(in track). Fasten to side
jamb of opening, using
screws provided. It may be necessary to
remove existing baseboard to ensure flush fit.
Install pivot door panel
Install the door by inserting the top pivot
into the pivot bracket in track. Lift the door
and seat bottom pivot into jamb bracket.
Install snugger guide
Insert snugger guide into the track.
Depress guide pivot and position under
track and release so guide pivot is securely
positioned in track.
Adjust door for height
Lift door and remove
bottom pivot
from jamb
bracket.
Rotate the
bottom pivot,
as required, to
adjust to
proper height.
Rotate clockwise to
raise the door; counter-clockwise to lower
it. Do not attempt to turn pivot while
engaged in the jamb bracket.
Adjust door to be plumb
Lift door and slide bottom pivot into
desired position. Using screwdriver, loosen
screw in top pivot bracket and slide it until
door is plumb. Tighten screw in top pivot
bracket.
Door pull
Drill hole for door
pull in center of
guide door panel
at suitable height.
NOTE: For raised
panel bifolds,
placement
may vary
by profile.
Attach
aligners
For 4-panel
installation
only.
Attach
aligners to back
of guide door panels, approximately 12”
(30cm) from the floor. Adjust in or out in
slotted holes until doors “snap” closed.
Tighten screws.
Adjustment for 4-panel installation
On 4-panel installation, doors may be
“snugged” independently, if desired. Drive
a screw partially into the track at the
center of the opening to act as a stop for
the two slide guides.
Cross-section and trim options
Note: For best performance of your bifold
doors, the track should not be painted. If
you wish, a silicone lubricant may be
applied for even smoother operation.

Use a wood strip to conceal
bifold hardware if desired.
