 Industrial Specialty Doors

Sally Port doors on correctional facilities are known for repeated opening and closing cycles, as many as 200 to 300 times a day. From experience you can depend on our Four-Fold Doors and Bi-Fold Doors for over two million cycles with minimal preventive maintenance.

There's always a possibility of vehicle and door damage on high usage doors. EPD four-fold doors and bi-fold doors reduce the likelihood of these problems by rapidly moving the door panels in a sideways direction keeping the door panels in the sight-line of the driver. The quick two-feet-per-second opening and closing speed also reduces the chances of damage.
