Sugatsune introduces the new Aileron Lid Stay Hinge System, engineered to make an installation easy and flexible, says the company. The system allows for smooth and easy door movement with lift assist, free stop and soft-close functions. It is mounted to the top of the cabinet, so no side boards are needed, while allowing for wider cabinets. The lid stay technology includes a five-speed adjustment and can be used with upward opening cabinets for kitchens or toy chest/bench seating.
