These variable overlay hinges are designed for face-frame cabinets and are meant for doors that have a flat back (will not work on cabinet doors with an inset. Please review the images). Made from durable steel for long-lasting strength, these hinges feature a self-closing dual-spring mechanism that ensures doors close quickly and stay firmly shut. Each pack includes two hinges, complete installation hardware, and door bumpers to soften closure noise. Ideal for kitchens, bathrooms, or any cabinetry project requiring reliable performance and easy installation.
