This cabinet hinge has the following installation specifications: cup diameter of 35mm, cup depth of 11.5mm, screw hole distance of 45mm, and opening angle of 105 degrees, making it suitable for most cabinet door styles. Each hinge comes with 2 easy-on dowels and 3 self-tapping wooden screws to ensure a perfect fit during installation. The hinge is equipped with a built-in POM damper to achieve a soft-close function. It reduces the closing speed, minimizes kitchen noise, and extends the service life of doors, cabinets, and hinges. Additionally, it supports a small soft-close angle, which better protects your fingers.Featuring an upgraded 4D adjustment function, the cabinet door can be adjusted in four dimensions—vertical, horizontal, depth, and closing speed—simply by turning a screwdriver. This ensures that custom-made cabinet doors do not sag, align properly, and open and close smoothly. The closing speed can be adjusted freely within 0-7 seconds.Made of high-quality steel, the hinge undergoes double electroplating treatment, with a nickel-plated finish and a brass-plated base. It is durable and suitable for connecting high-end doors such as kitchen cabinet doors, wardrobes, TV cabinets, bookcases, and wine cabinets.
