Security Doors for Sally Ports
Sally Port doors on correctional facilities are known for repeated opening and closing cycles.
As many as 200 to 300 times a day. That’s why EPD's Four-Fold and Bi-Fold Doors have been so popular. You can depend on their operation for over two million cycles with minimal preventive maintenance.
EPD doors last 20 to 30 times longer than conventional doors
130 Correctional facilities in 47 states have installed EPD's security doors since 1990.
There's always a possibility of vehicle and door damage on high usage doors.
EPD's four-fold 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.
Four-Fold Doors can have a variety of custom designed panels to make them match the design of any building:
Flat or pre-formed steel
Bars or round rods
Bullet resistant panels
EPD doors for correctional facilities can include a variety of automated controls and locking systems.
EPD has worked closely with the Federal Bureau of Prisons to develop and manufacture automatic attack-resistant locking mechanisms designed to meet security and riot control criteria.
