FFI excels in hardware for lift-slide doors and windows, interior and exterior sliding doors, and window locks and accessories - with many components in stainless steel (SST), architectural bronze, and aluminum with durable class I anodizing and kynar paint. Our decorative hardware features in-demand finishes such as satin nickel and oil-rubbed bronze.

FFI has been an official distributor for Truth Hardware since 1987, including window operators, roto hardware, Anderberg 4-bar hinges, and patio door rollers.

Many FFI products are well-suited to Green building and LEED certified projects, and facilitate goals for natural light, ventilation and energy savings. Learn more
