EPD 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
  • Louvers
  • Security mesh
  • Bullet resistant panels
  • Vision lights

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.
