INSPECT FINISHED OPENING
• The width size specification (finished opening size) shown on the
bifold packaging is 1/2" larger than the bifold set to allow for at least
a 1/4" gap between the side jamb and pivot door (door secured to
the floor and head jamb). Double units should have at least 1/4" gap
between both side jambs and no gap between the doors that meet in
the middle.
• The height size specification (finished opening size) shown on the
bifold packaging is 1 1/2" larger than the bifold set to allow for
the track to be installed above the door set and the lower bracket
installed below the door set.
• Measure height and
width of finished
wall opening and
verify it is no more
than 1/4" larger or
smaller than the
stated opening size
on the packaging.
• Once the door
set(s) are installed,
there is an
additional hardware
adjustment of up to
3/8" to center the
sets in the finished
opening.
• If the finished
opening is too large,
filler material, such
as a 1" x 6" piece
of pine trim can be
tacked into the opening to bring it to the correct size.
• If the finished opening is too small (1/2" or less), 1 3/8" thick hollow
or solid core molded and flush doors may be trimmed 1/4" on each
side as necessary. Trimming any other bifold type is not recommend.
• If the opening is too far out of specification, or if you are
not confident trimming, you can order custom sizes from our
manufacturing locations to fit the finished opening, or contact a
building professional for assistance. Contact us or a dealer/distributor
for options.
