Engineered for maximum glass visibility and superior functionality, the versatile Bi-Fold WA6400 system can combine up to 12 panels in openings up to 36 feet. With a range of configuration options to choose from, this system allows for both flexibility and creativity when designing spaces.

The Bi-Fold WA6400 uses European hardware that has been exclusively manufactured for Reveal Windows & Doors. The exceptionally durable system features hinges that are interlocked into the aluminum rather than screwed onto the wood face to prevent sagging. The panels can be adjusted for easy operation and a precise fit.

The Bi-Fold WA6400 comes with extruded aluminum cladding for a long-lasting, low-maintenance exterior. A variety of finishes are available, including custom color-matched Kynar® (suitable for harsh coastal environments) and clear-anodized or bronze-anodized options.
