IMPORTANT INFORMATION AND GLOSSARY
INSTALLATION INSTRUCTIONS
for Bifold Doors (JII103)
Thank you for selecting JELD-WEN® products. Attached are
JELD-WEN’s recommended installation instructions for hollow
and solid core bifold doors. Bifolds are designed for fast and
easy installation and adjustment using common tools.
Read these installation instructions thoroughly before beginning. They
are designed to work in most existing applications. However, existing
conditions may require changes to these instructions. If changes are
needed, they are made at the installer’s risk. For installations other than
indicated in these instructions, contact a building professional.
Note to Installer: Provide a copy of these instructions to the building
owner. By installing this product, you acknowledge the terms and
conditions of the limited warranty as part of the terms of the sale.
GLOSSARY

The resulting opening after any trim work is completed. Measure these
dimensions for proper door tting.

assemblies, these are the two that meet in the middle.

SAFETY AND HANDLING
• Read and fully understand ALL manufacturers’ instructions before
beginning.
• Use safe lifting techniques.
• Wear protective gear (e.g. safety glasses, gloves, ear protection, etc.).
• Operate hand/power tools safely and follow manufacturer’s operating
instructions.
• Heed material manufacturers’ handling and application instructions.
• Store doors in a dry, well-ventilated building and on a at and level
surface.
• Do not subject interior doors to extremes of heat and/or humidity.
Prolonged exposure may cause damage. Buildings where humidity
and temperature are controlled provide the best storage facilities
(recommended conditions 30%-50% Relative Humidity and 50°F to
90°F).
• Do not install doors in buildings that have wet plaster or cement
unless they have been properly nished. Do not store doors in
buildings with excessive moisture content - HVAC systems should be
operating and balanced. Avoid sudden changes such as forced heat
to dry out a building. Doors should not be delivered to the job site
or installed until concrete oors, foundation, plaster or drywall are
cured.
• Doors should always be handled with clean hands or while wearing
clean gloves.
• Doors should be lifted and carried when being moved, not dragged
across one another.
• Finish all six sides (both sides and all four edges) of the door slab,
including cutouts for hardware. Failure to nish all six sides may
result in the denial of warranty claims for operational or performance
problems.
IF INJURY OCCURS, IMMEDIATELY SEEK MEDICAL ATTENTION!
