Setup and Installation
Tools Required
- Screwdriver (appropriate type for mounting screws)
- Measuring Tape
- Pencil
- Drill (optional, for pilot holes)
- Chisel (if mortising is required)
Installation Steps
- Preparation: Ensure the door frame and door edge are clean and free of debris. If replacing existing hinges, remove the old hardware.
- Positioning: Determine the correct placement for each hinge on the door and frame. Standard practice is to place hinges approximately 7 inches from the top and 11 inches from the bottom of the door, with a third hinge centered if applicable.
- Mortising (if required): If the hinges are to be mortised (recessed), carefully mark the outline of the hinge on both the door and the frame. Use a chisel to create a recess that allows the hinge to sit flush with the surface.
- Attaching to Door: Align the hinge leaf with the marked position on the door. Use a pencil to mark the screw hole locations. Drill pilot holes if necessary to prevent wood splitting. Secure the hinge leaf to the door using the provided screws.
- Attaching to Frame: Position the door within the frame, ensuring proper alignment and gap. Align the other hinge leaf with the marked position on the door frame. Mark and drill pilot holes, then secure the hinge leaf to the frame.
- Final Adjustment: Close the door slowly to check for proper operation. Adjust screws as needed to ensure smooth movement and a consistent gap around the door.

Operating Instructions
Once properly installed, the MPB79 bearing hinges are designed for smooth and quiet door operation. No specific operational steps are required beyond opening and closing the door.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your hinges.
- Cleaning: Wipe hinges periodically with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners that may damage the satin chrome finish.
- Lubrication: If hinges begin to squeak or stiffen, apply a small amount of silicone-based lubricant to the hinge pins. Open and close the door several times to distribute the lubricant.
- Tightening Screws: Periodically check all mounting screws and tighten them if they have become loose. Loose screws can lead to door sagging or misalignment.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door Squeaks | Lack of lubrication | Apply silicone-based lubricant to hinge pins. |
| Door Sags or Drags | Loose mounting screws | Tighten all hinge mounting screws. |
| Door Does Not Close Properly | Misalignment during installation, bent hinge | Check hinge alignment and adjust if possible. Inspect hinges for damage; replace if bent. |
