The Bi-Fold unit allows for ventilation in kitchens, boiler rooms and areas where a screen door is not practical. Panels fold out of the opening and attach securely to each other and the door magnetically. Four cam-locks secure the bi-fold in the closed position. Many of our current FRP face sheets can be used to match door exterior. Refer to color charts for standard colors offered. Face sheets can also be painted any custom color.
A standard SL-BF350 bi-fold unit contains an insect and vandal screen. Other options available include installing a security grate in place of the vandal screen. Consult factory for more details.
Refer to detail drawing of the Bi-Fold unit for further clarification on construction.
