Upgrade your cabinets with the Berta 4D Adjustable Soft-Close Concealed Cabinet Hinges, designed for precise alignment, quiet operation, and long-lasting durability. The advanced 4D adjustment system allows you to fine-tune vertical, horizontal, depth, and closing speed settings with only a screwdriver, making installation easier and helping cabinet doors stay perfectly aligned without sagging. Each hinge features a built-in POM hydraulic soft-close damper that provides smooth and quiet closing action while reducing slamming, noise, and stress on cabinet doors and frames. The additional small soft-close angle protection helps improve safety by minimizing the risk of pinched fingers during daily use. Made from durable materials and designed for standard cabinet applications, these hinges feature a 35 mm cup diameter, 11.5 mm cup depth, 45 mm hole spacing, and a 105-degree opening angle. Every hinge includes mounting dowels and self-tapping screws for quick and secure installation, making them an excellent choice for kitchen, bathroom, laundry room, and other face-frame cabinet projects.
