Functional Fenestration has a wide collection of architectural hardware for doors, windows and skylights – carefully selected for high quality, aesthetics, and variety. FFI's inventory includes custom products of our own design, and from numerous manufacturers around the world, including European hardware lines from AGB, Olivari, and Tiger. FFI has been an official distributor for Truth Hardware since 1987, including window operators, Anderberg 4-bar hinges, and patio door rollers.

Window and door manufacturers, custom millworks, hardware dealers, and architects rely on FFI for uncompromising quality. Our custom-manufactured door hardware and window hardware products benefit from intensive research and product development.

FFI excels in systems for lift slide, interior and exterior sliding doors – with many components in stainless steel and architectural bronze, and in-demand finishes like kynar and oil-rubbed bronze. Also, FFI specializes in electric actuators for motorized windows and skylights – with Truth motors and UCS motors providing a range of products and capacities from residential to heavy commercial vents.

FFI is committed to customer satisfaction, strong technical support, and on-hand inventory. We are here to help, because FFI believes that our success is based on your success.
