All the weight of the
Stack Door is on the bottom track, unlike the bi-fold door, which
the weight of their door overhead. That means a savings to you because
of the extra expense
required for the building manufacture for the end wall loading needed
to accept the weight of
the bi-fold door.
Stack Door is manually operated door system, that glides on patented
truck assemblies located
on every other panel. Each truck assembly has 6 heavy duty sealed
bearing, two riding on the
top of the track and two riding one each side of the track. This
design eliminates friction on all
three sides of the bottom track, for a smooth operation. Due to the
fact that power operators are not required, you eliminate the problems
with power failures.
Bi-fold doors and power operated sliding doors require the extra
expense of electrical wiring
needed for their power operators. Another savings on your overall
when using the Stack Door.
Designing the building to accept the Stack Door will hold down the
overall building height.
The framed opening height is the clear opening height. That translated
into another savings
on the overall building cost.
Bi-fold doors, open to the top of the building consuming a minimum of
2' overhead space,
even on the smallest of openings.
Stack Door folds to the left and right side of the framed opening, and
a straight 90 degrees
from the face of the building, out of the way. This design allows for
a partial opening,
you can open on half of the door, just two panels, or the entire door
for your convenience.
Some sliding doors are top hung, some carry the weight on the bottom
track. All present
design problems of the out riggers, or limit your design on the
placement of windows and
or personnel doors.
Helping you save on the installation of the door system, the Stack
Door is shipped assembled
The exterior of the door is skinned with an 8oz. Solar Gray, Kaiser
Twin Ribbed Fiberglass. The
fiberglass skin floods the inside of the building with light, skin has
a 40% transparency. this insures an
additional labor savings, by eliminating the need for your crews to
skin the door at the job site.

bottom weighted door, manually
operated, lower building height, partial openings, shipped assembled
and skinned, and all that natural
light, specify the Stack Door on your next building project.
