Specifications are configurable for OEM/ODM orders. Exact values are confirmed on the datasheet for your order.
How to Choose
- Cup diameter (35mm is the furniture-industry standard; 26mm for thin doors)
- Cup depth and the required boring pattern
- Opening angle (95°–110° for most doors, wide-angle for blind corners)
- Overlay type: full overlay, half overlay, or inset
- Face-frame vs frameless (European) cabinet construction
- Door thickness and material
- Soft-close or self-closing requirement
- Mounting plate type and clip-on vs screw-on attachment
Material Options
Cold-rolled steel arms with nickel plating are standard for value, while stainless steel suits humid kitchens and bathrooms. Cup and arm gauge drive the cycle life and sag resistance.
Finish Options
Hinges are usually nickel-plated and hidden inside the cabinet, so finish is about corrosion resistance rather than appearance. Specify a heavier plating or stainless steel for high-humidity programs.

Installation Notes
Bore the 35mm cup, screw the hinge boss to the door, fix the mounting plate to the cabinet side at the correct height, then clip the arm to the plate. Use the three adjustment screws to align overlay, height, and depth.
