IMPORTANT INFORMATION AND GLOSSARY
GLOSSARY

dimensions for proper door tting.

SAFETY AND HANDLING
SAFETY AND HANDLING
• Read and fully understand ALL manufacturers’ instructions before 
beginning.
• Wear protective gear (e.g. safety glasses, gloves, ear protection, etc.).
• Store doors in a dry, well-ventilated building and on a at and level 
surface. Allow doors to acclimate to local conditions for at least 24 
hours before nishing.
• Do not subject 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. Use safe lifting techniques.
IF INJURY OCCURS, IMMEDIATELY SEEK MEDICAL ATTENTION!
FINISHING
These are guidelines for nishing doors. For more detailed instructions 
visit a local paint professional.
• Clean the door with a clean, lint-free cloth, removing all dust and 
foreign debris.
• 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.
• Use a good quality primer and paint, or wood sealer and stain. Pre-
primed products do not need to be re-primed. Use one manufacturer’s 
products to ensure compatibility and follow all manufacturers’ 
application instructions.
INSPECT DOOR AND OPENING
• Cosmetic damage, correct product (size, color, design, etc.)
• Measure height and width of nished wall opening. Width must be 
1/2" larger than the bifold size. Height must be approximately 1 1/2" 
taller. If shorter, the bifold doors cannot be installed. If higher, shorten 
by nailing a wood strip at the top of the opening.
• Doors may be trimmed 1/4" on each side if necessary.
