Preparing the Cabinet and Door for Installation

Before attaching concealed hinges, it’s essential to prepare both the cabinet frame and the door with precision. Begin by measuring the door thickness and the hinge cup diameter to confirm compatibility. Most concealed hinges require a 35mm diameter cup hole, but variations exist depending on the hinge model.

Mark the location for the hinge cups on the back of the door. Typically, hinges are positioned about 3 to 4 inches from the top and bottom edges of the door. For wider doors, consider adding a third hinge in the center to ensure proper support and alignment. Use a pencil and a template or jig to ensure consistent and accurate markings.

When drilling the cup holes, use a Forstner bit matched to the hinge cup size. The depth of the hole is generally around 12 to 13mm but verify with the hinge manufacturer’s specifications. Drill carefully to avoid splintering the wood surface.

On the cabinet frame, mark the mounting plate locations corresponding to the hinge cups on the door. These are usually installed inside the cabinet frame, aligned with the door edges. Use a square to ensure that the mounting plates will be level and parallel to the cabinet opening.

Attaching the Hinge Cups to the Door

Once the holes are drilled, insert the hinge cups into each hole on the door. The cups should sit flush with the back surface of the door without gaps. Secure the hinge cups using screws provided with the hinge set, typically small Phillips head screws.

Ensure screws are tightened firmly but avoid over-tightening, which can strip the wood or deform the hinge cup. After securing, gently test the hinge cup to confirm it is stable and immobile.

If the door requires multiple hinges, repeat this process at each marked location. Double-check that all hinge cups are aligned vertically to prevent uneven door operation.

Mounting the Hinge Plates Inside the Cabinet

With hinge cups attached to the door, the next step is to mount the corresponding hinge plates inside the cabinet. Position each mounting plate at the marked locations on the cabinet frame.

Use a drill to pre-drill pilot holes for the mounting screws. This helps prevent wood splitting and ensures accurate screw placement. Insert screws and tighten securely.

Check that the mounting plates are flush with the cabinet surface and aligned so the door will sit square when hung.

Hanging and Adjusting the Door

To hang the door, align the hinge cups on the door with the mounting plates inside the cabinet. Most concealed hinges have a clip-on or snap-on mechanism that allows the door to be easily attached or detached from the mounting plates.

After snapping the door into place, adjust the hinges to achieve proper alignment. Concealed hinges typically offer three-way adjustability:

  • Height adjustment: Moves the door up or down.
  • Side-to-side adjustment: Aligns the door horizontally.
  • Depth adjustment: Controls the gap between the door and cabinet frame.

Use a screwdriver to turn the adjustment screws on the hinge to fine-tune the door position. Check that the door opens and closes smoothly without binding or excessive gaps.

Troubleshooting Common Installation Issues

During installation, some common problems may arise. Address them as follows:

  • Door misalignment: Adjust the side-to-side and height screws to correct uneven gaps.
  • Door rubbing on the cabinet frame: Increase depth adjustment to move the door outward.
  • Loose hinge cups: Ensure screws are tight and the cup hole is clean and properly drilled.
  • Hinge not closing fully: Check for obstructions or misaligned mounting plates.
Issue Cause Solution
Door unevenly aligned Incorrect hinge placement or adjustment Adjust height and side screws; re-check hinge positioning
Door binding or sticking Insufficient depth clearance Increase depth adjustment; ensure mounting plate is flush
Loose door Loose hinge screws Tighten all screws; replace damaged screws if necessary
Hinge cup not flush Incorrect drill depth or hole diameter Redrill hole with correct size and depth; fill and repair if needed

Preparing the Cabinet Door and Frame for Concealed Hinges

Installing concealed hinges requires precise preparation to ensure a clean, functional, and durable fit. Begin by selecting the appropriate hinge type that matches your cabinet door thickness and overlay style. Most concealed hinges are designed for standard door thicknesses of 16–19 mm and offer various overlay adjustments.

Careful measurement and marking are critical steps before drilling or cutting:

  • Determine the hinge cup location: Typically, the hinge cup is recessed into the back of the cabinet door about 3–5 mm from the edge, centered vertically approximately 22–25 mm from the top and bottom edges.
  • Mark the drilling points: Use a template or jig to mark the exact position for the hinge cups on the door. This ensures consistent placement and alignment.
  • Prepare the cabinet frame or carcass: Mark the corresponding locations where the hinge mounting plates will attach, considering the overlay and door swing direction.

Use the following table as a reference for standard hinge cup drilling dimensions:

Measurement Typical Value Notes
Hinge cup diameter 35 mm Standard concealed hinge cup size
Hinge cup depth 11–13 mm Depth needed to recess hinge cup into door
Distance from door edge to cup center (bore distance) 3–5 mm Ensures door edge clearance and proper overlay
Vertical distance from door top/bottom edge 22–25 mm Position for hinge cups for stability and aesthetics

Ensure the cabinet door is clean and free from debris before proceeding to drilling.

Drilling the Hinge Cups and Attaching Hinges to the Door

Precision drilling is essential to achieve a flush and secure hinge installation. Use a Forstner bit or hinge boring bit sized exactly to the hinge cup diameter (usually 35 mm) to create clean, flat-bottomed holes.

Follow these steps:

  • Clamp the door securely on a workbench to prevent movement during drilling.
  • Set the drill depth using a depth stop or tape on the drill bit to avoid drilling through the door. The depth should match the hinge cup depth (11–13 mm).
  • Align the drill bit center with the marked cup location, maintaining perpendicularity to the door surface.
  • Drill the hinge cup holes carefully, ensuring smooth edges and correct depth.
  • Test fit the hinge cups to verify the fit is flush and snug.

After drilling:

  • Insert the hinge cup into the hole.
  • Secure each hinge cup using the screws provided, generally two screws per hinge cup.
  • Use a screwdriver or drill with a clutch setting to avoid over-tightening and damaging the door material.

Mounting the Hinge Plates on the Cabinet Frame

The hinge mounting plates attach to the cabinet carcass and interface with the hinge arm on the door. Proper placement and secure attachment of these plates are vital for smooth door operation.

Steps for mounting the hinge plates:

  • Refer to the hinge overlay and door swing direction to position the mounting plates correctly.
  • Mark the mounting screw holes on the cabinet frame or side panel using the hinge plate as a template.
  • Pre-drill pilot holes if working with hardwood or particleboard to prevent splitting.
  • Attach the hinge plates with screws, ensuring they are tight and flush with the cabinet surface.

Adjustability is a key feature of concealed hinges. Most hinge plates allow for:

  • Horizontal adjustment (side to side)
  • Vertical adjustment (up and down)
  • Depth adjustment (in and out)

This flexibility enables precise door alignment after installation.

Attaching the Cabinet Door and Adjusting the Hinges

With hinges mounted on both the door and cabinet frame, the final step is to connect the door and fine-tune the alignment.

  • Clip or screw the hinge arm onto the mounting plate depending on the hinge design. Many concealed hinges use a clip-on mechanism for easy installation.
  • Check the door alignment for gaps, height, and overlay consistency.
  • Use the hinge adjustment screws to:
  • Move the door horizontally to align edges.
  • Adjust the door height to level it with adjacent doors or cabinet edges.
