How to Adjust a 3D Soft-Close Concealed Cabinet Hinge
Cabinet door gaps uneven or soft-close not sitting right? Learn the safe checks for side, height, and depth adjustment on 3D concealed hinges.

What 3D adjustment means
A 3D concealed hinge lets you adjust the cabinet door in three directions: side-to-side, up-and-down, and in-and-out from the cabinet. This is useful when a door gap looks uneven, the door rubs the cabinet, or two neighbouring doors do not line up.
Many modern concealed hinges use a 35mm cup bored into the door. The Baifeibu 3D Adjustable Soft-Close Concealed Cabinet Hinge listed in the catalogue is one example where the product photo confirms a 35mm cup, 3D adjustment, and soft-close wording on the packaging.
Before you turn any screw

Open and close the cabinet door slowly. Check whether the issue is the hinge adjustment or the door itself. If the screws are loose, the door is warped, or the cabinet side is damaged, adjustment alone may not hold for long.
Identify the model and each adjustment control before turning it. Screw positions, directions and limits vary; an illustrative photograph is not a screw map for every hinge. Support the door and do not release a fixing or clip unintentionally. Use a correctly matched hand screwdriver rather than a drill for final adjustment. Small turns are easier to control, and they reduce the risk of stripping the screw head or over-moving the hinge.
Side adjustment
Side adjustment moves the door left or right. Use it when the gap between two cabinet doors is uneven, or when the door edge is too close to the side panel. Turn the adjustment screw a small amount, then close the door and check the gap again.
If two doors meet in the middle, adjust both doors gradually rather than pushing one door too far to compensate for the other.
Height adjustment
Height adjustment moves the door up or down. Some plates use a cam adjustment; others require controlled repositioning at slotted fixing holes. Follow the exact plate instructions instead of loosening screws by default. Support the door, keep the hinge securely engaged and stay within the permitted adjustment range.
Height adjustment is useful when one cabinet door sits lower than the next one, or when the top and bottom gaps are not level.
Depth adjustment
Depth adjustment moves the door closer to or farther away from the cabinet frame. Use it when the door sits proud, rubs the frame, or does not close flush. Adjust in small steps and test the soft-close action after every change.
If a soft-close hinge suddenly starts slamming, first check whether the hinge is aligned and fully seated. If the damping mechanism has failed internally, adjustment may not restore the soft-close action.
When to replace instead of adjust
The cup hole in the door is broken or enlarged
Screws no longer grip the cabinet side
The hinge arm is bent
The soft-close action no longer works after alignment checks
The door is too heavy for the number or type of hinges fitted
Buying checklist for replacement hinges
Cup size, usually 35mm on many concealed cabinet hinges
Overlay type: full overlay, half overlay, or inset
Door thickness
Soft-close or standard close
Quantity of hinges per door
Existing hinge photo from front, side, and mounting plate
For replacement work, bring one old hinge or send clear photos before ordering a full set. Matching the cup size, overlay, and mounting plate saves a lot of fitting time.
