For homeowners and installers alike, one of the biggest frustrations with concealed door hinges is alignment: even a tiny misstep during installation can lead to doors that stick, rub, or won’t close properly. That’s why we developed the C128-110 3D concealed hinge—engineered to solve alignment issues with its unique 3D adjustment capabilities, while delivering the durability and seamless look that define high-quality concealed hardware.
3D Adjustment: Fix Alignment Issues with Ease
The standout feature of the C128-110 3D is its fully adjustable 3D mechanism—something that sets it apart from standard concealed hinges. Most concealed hinges only offer limited adjustment (if any), forcing installers to rely on perfect routing and frame alignment to get the door right. The C128-110 3D changes that by allowing precise adjustments in three directions: height (±2 mm), depth (±1 mm), and side (±1.5 mm). This means even if the routing is slightly off or the frame shifts over time, installers can fine-tune the hinge to get the door sitting perfectly. For example, if a door rubs against the frame on the top edge, a quick adjustment to the height setting can fix the issue—no need to reroute the door or adjust the frame. As a concealed door hinges supplier, I’ve seen how this feature saves installers hours of work and reduces frustration, while ensuring homeowners get a door that operates smoothly.
Specs That Deliver: Load Capacity and Versatility
Beyond adjustment, the C128-110 3D is built to perform in real-world residential settings. Let’s start with load capacity: when two hinges are installed, it can support doors up to 45 kg (99 lbs)—plenty of strength for most interior doors, including solid wood doors, painted doors, and even light steel-framed doors. This load capacity is achieved through its zinc alloy construction, which balances strength and lightweight performance—ensuring the hinge doesn’t add unnecessary weight to the door while still being durable. The hinge also offers impressive versatility in terms of door compatibility: it fits doors with a minimum thickness of 36 mm (1.417 inches) and a maximum thickness of 850 mm (33.464 inches), making it suitable for everything from standard bedroom doors to thicker closet or utility room doors. It works with both unrebated and rebated doors, and can be used with wood, steel, and other common door frame materials—so it’s a one-size-fits-most solution for residential projects. We also designed it with a 180° opening angle, giving homeowners full access to the space behind the door—no more struggling with doors that only open partially.
