The 3EA is typically used for small to medium size store fronts, larger counter shutters, or any other wall openings up to 18' wide by 10' high. The 3EA can be hand operated up to 13' wide by 8' high, while a tube motor is used up to the maximum size.

The 3EA provides many architecturally-appealing options. In addition to the solid slat, it can be slotted to provide visibility or air flow. Once slotted, a polycarbonate insert can be added to keep the visibility while restricting the airflow.


  • Curtain - Constructed using 75mm interlocking extruded aluminium slats. The slats are retained in position using nylon end clips. Slotting options are available.

  • Track - Aluminum extruded track mounts to steel mounting angle which also accepts the head plate above.
  • Roller Drum - A 4" steel tube provides a fairly compact roll while reducing deflection.

  • Locking - Several locking option are available of which the most common are the keyed (either at waist height or on the bottom rail) and the shoot bolts (inside or outside).
