1. What are full cover, half cover and large bend? (Overlay)
This is the most commonly misordered parameter. According to the extent to which the cabinet door covers the side panel after closing, it is divided into three types:
Full Cover (Full Overlay/straight bend): The cabinet door completely covers the side panel (usually covering about 18mm), suitable for single-opening cabinets.
Half Cover (Half Overlay/medium bend): Two cabinet doors share one side panel, and each door covers half of the side panel (about 9mm).
Inset (Large Bend): The cabinet door retracts into the cabinet body when closed, with the side panel fully exposed.
Standard size: The majority of modern furniture uses 35mm.
Special size: Small cabinets, mirror cabinets or thinner cabinet doors may use 26mm.
Tip: Before drilling, make sure that the 26mm hinge can fit into the 35mm hole.
2.What angle should be chosen for the door opening?
Standard angle: 95° - 110°, suitable for the majority of wardrobes and cabinets.
Special angle: Corner cabinets may require 165° - 175° (an extremely large opening angle), or specific irregular angles such as 45°, -45°.
3. How to solve the problem of "not closing tightly" or "tilted" of the cabinet door? (Three-dimensional adjustment)
The greatest design of invisible hinges lies in their three-dimensional adjustment function, usually consisting of three screws:
Left and right adjustment: Adjust the front-end screws on the hinge arm to change the size of the door gap.
Up and down adjustment: Adjust the screws on the base (or loosen the up and down sliding of the base), adjust the height of the cabinet door.
Front and back adjustment: Adjust the screws at the rear end of the hinge arm to solve the gap between the door and the cabinet body, preventing the door from not closing tightly.
4. What is the difference between self-unloading (Clip-on) and fixed (Slide-on)?
Self-unloading (quick-install): There is a spring button behind the hinge, pressing it can remove the door without removing the screws. It is convenient for later cleaning or installation.
Fixed: The door needs to be loosened by unscrewing the screws.
5. What is "hydraulic damping" (Soft-close)?
This is a standard feature of modern furniture. The hinge integrates a hydraulic cylinder inside.
Advantages: When closing to the end, it slows down automatically, silently closes and absorbs impact, preventing hand clamping and noise.
Question: Why does the damping weaken? Usually, it is due to low temperature causing changes in the viscosity of the hydraulic oil, or leakage of the hydraulic cylinder in cheap hinges.
