Woodfold Series 740

When you need to close off a space and lock it up tight, Alumifold Doors are a fast, secure way do it. When that space sees a lot of foot traffic, such as malls or public lobbies, Alumifold is the fast, secure, and stylish solution for storefronts or customer service desks. Easy to operate and dependable for years to come, these doors are available in either opaque panels or perforated. Opaque panels offer privacy and extra deterrence; perforated partitions are great for rooms that need the air exchange while staying locked (think IT rooms with hot servers and audible alarms). They’re also beautiful for installations requiring easy-to-clean, sleek-looking folding doors.

Alumifold doors are made from single-piece, extruded aluminum body panels for extra strength, and use our exclusive hardware hinge system featuring rigid vinyl and steel rod construction. Choose from Bronze, Gold or Clear (silver) finishes, with color coordinated panel connectors.
