Introducing the BI Series Folding Cabinet Door Support – Metal Flap Stay, a high-performance lift-up hinge system engineered for durability, smooth operation, and modern functionality in kitchen, bathroom, and premium furniture applications.

Designed for overhead, wall-mounted, and folding doors, this metal flap stay combines robust construction with intelligent mechanics. Featuring a hydraulic damper, it delivers soft-close operation to prevent slamming, and a free stop function that allows the door to hold securely at any opening angle — enhancing safety and convenience, especially in homes with children or high-traffic environments.

The push-to-open mechanism eliminates the need for handles or knobs, making it ideal for handleless, minimalist, and smart cabinetry designs.
