5. Installation Guide
These hinges are designed for easy, non-mortise installation, requiring only a screwdriver. No drilling is necessary for standard applications.
5.1. Understanding Hinge Types and Board Thickness
Refer to the diagram below to determine the correct hinge application based on your cabinet door and side board configuration. The hinges are suitable for board thicknesses between 12-21mm.
Image: Installation guide illustrating different hinge applications: Full Overlay, Inset, and Half Overlay. It provides measurements and recommendations for board thickness.
- Full Overlay: For side board thickness of 19mm, the door overlay is 19mm. For side board thickness of 17mm, the door overlay should be 17mm.
- Inset: The width below the door should be 4mm.
- Half Overlay (Not Recommended): This type requires adding extra depth to the side board and using longer screws, which can be complex and is generally recommended for professionals only.
5.2. Installation Steps
- Position the Hinge: Place the hinge on the inside of the cabinet door and the side panel according to your desired overlay type (Full Overlay or Inset). Ensure the hinge is flush with the edges where the door meets the cabinet frame.
- Secure Initial Screws: Install screws into the 4 adjustable screw holes first. These holes allow for minor adjustments to align the door correctly.
- Adjust Door Alignment: Gently close the door to check its alignment. Make small adjustments by loosening and tightening the screws in the adjustable holes until the door sits perfectly square and closes smoothly.
- Install Remaining Screws: Once the door is properly aligned, install the remaining screws into the fixed holes to fully secure the hinge.

6. Operation
The Lancher Non-Mortise Concealed Hinges allow for a 90-degree opening of cabinet doors. They feature a spring-loaded self-closing mechanism, which means the door will automatically pull itself shut when pushed close. Please note that these hinges are not soft-close hinges; they will close with a distinct snap. If a soft-close feature is desired, external cabinet door dampers can be installed separately.

7. Maintenance
To ensure the smooth operation and longevity of your Lancher hinges, follow these simple maintenance guidelines:
- Regular Cleaning: Wipe the hinges periodically with a soft, dry cloth to remove dust and debris. Avoid abrasive cleaners or harsh chemicals that could damage the zinc-plated finish.
- Lubrication: If the hinges begin to squeak or feel stiff, apply a small amount of silicone-based lubricant to the pivot points. Do not use oil-based lubricants as they can attract dust.
- Check Screws: Periodically inspect all mounting screws to ensure they are tight. Loose screws can lead to door misalignment or hinge failure.
- Avoid Overloading: Do not exceed the recommended weight capacity of 20 lbs per door. Excessive weight can strain the hinges and lead to premature wear.
8. Troubleshooting
If you encounter issues with your Lancher hinges, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Door does not close completely or springs open slightly. | Misalignment; cabinet or door warped; insufficient spring tension for door weight. | Check door and cabinet for squareness. Loosen adjustable screws, reposition door, and retighten. Ensure door weight does not exceed 20 lbs. If the issue persists, consider adding a magnetic catch. |
| Door sags or is not level. | Loose screws; heavy door exceeding weight limit; improper hinge placement. | Tighten all screws. Verify door weight is within the 20 lbs limit. Ensure hinges are installed level and plumb. For very wide or heavy doors, additional hinges may be required. |
| Hinges squeak or operate roughly. | Lack of lubrication; dirt or debris. | Clean hinges and apply a silicone-based lubricant to pivot points. |
| Hinge appears loose or wobbly. | Loose screws; hinge mechanism wear. | Ensure all screws are securely tightened. If the hinge itself has excessive play, it may need replacement. |
