t The width size specication (nished 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 oor
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.
t The height size specication (nished 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.
t Measure height and width
of nished wall opening
and verify it is no more than
1/4" larger or smaller than
the stated opening size on
thepackaging.
t Once the door set(s) are
installed, there is an additional
hardware adjustment of up to
3/8" to center the sets in the
nished opening.
t If the nished opening is too
large, ller material, such as a
1" x 6" piece of pine trim can
be tacked into the opening to
bring it to the correct size.
t If the nished opening is
too small (1/2" or less),
1-3/8" thick hollow or solid
core molded and ush doors may be trimmed 1/4" on each side as
necessary. Trimming any other bifold type is not recommended. For
the best appearance, trim an equal amount from opposite sides. To
minimize chipping, stick masking tape along the cut line to each face of
the slab. Make the cuts with a ne toothed circular saw.
