Installation Guide

INSTALLATION INSTRUCTIONS FOR 1-3/8” 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 finish-
ing 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.

Not all sizes are available in all markets as a stock item. Some sizes are only available through special order.
EXISTING FINISHED OPENING
If your finished opening is non-standard and you cannot fit your bifold into this opening, you will have
to contact your dealer so that a custom-sized bifold can be ordered from Masonite

How to Install your Bifold Doors:

of folding door installation. The same instructions also
apply to all types of door panels.
1
Measure exact height and width of finished opening.
Finished Opening ________________ high
________________ wide
2
Cut track
If necessary, cut
track to 3 mm (1/8”)
less than the width of
the finished opening.
Use a fine tooth
hacksaw.
3
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.
4
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.
5
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.
6
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.
7
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.
8
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.
9
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.
10
Door pull
Drill hole for door pull
in center of guide door
panel at suitable height.
NOTE: For molded panel
bifolds, placement may
vary by profile.
11
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.
12
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 snugger guides.
13
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.
