The Spiral Door’s crisp lines give this door a stylish look that’s
great with for all kinds of commercial, institutional as well as
industrial applications. Because the door’s anodized
aluminum finish will not corrode, you can count on that look to last for years under even the worst weather

to fit in anywhere. As for fit, the door’s tight profile takes up little room at the sides and along the header.
In-Room Energy and Intruders Where They Belong
High-speed operation controls the air exchange so less energy is required to maintain building temperature. The
door’s aluminum slats have a durable rubber membrane covering their connecting hinges, to contain heating/
cooling energy and preventing air infiltration. This tight seal stops dust pollution, drafts and inclement weather.
This same design also provides an effective barrier against unauthorized personnel. The door’s fast speed
confines access to traffic that belongs in the building.

® door controller takes performance to a whole new level. The
intelligent processor and variable frequency drive generate an energy efficient speed curve for smooth motion,
soft starting and soft stopping. Electronics replace high maintenance parts for reliable operation, less
downtime and greater control.
