• Screws for installation (quantity sufficient for 3 hinges)

Setup and Installation

Tools Required:

• Pencil
• Measuring Tape
• Drill with appropriate drill bits (for pilot holes)
• Screwdriver (manual or power, compatible with screw heads)
• Chisel and Hammer (if mortising is required and not pre-cut)

Installation Steps:

1. Prepare the Door and Frame: Ensure the door and door frame are properly prepared with mortises (recesses) for the hinges. If not pre-cut, mark the hinge locations (typically 7 inches from the top, 11 inches from the bottom, and one in the middle for a standard 80-inch door) and carefully chisel out the mortises to the depth of the hinge leaf. The hinge should sit flush with the surface.
2. Attach Hinges to Door: Place one hinge leaf into its mortise on the door edge. Ensure it is flush and aligned correctly. Mark the screw hole locations with a pencil. Drill pilot holes for each screw to prevent wood splitting. Secure the hinge leaf to the door using the provided screws. Repeat for all hinges on the door.
3. Position the Door: Carefully position the door within the door frame, aligning the hinges on the door with their corresponding mortises on the door frame. You may need assistance to hold the door steady.
4. Attach Hinges to Frame: Once the door is correctly positioned and aligned, mark the screw hole locations on the door frame through the hinge leaves. Drill pilot holes. Secure the hinge leaves to the door frame using the provided screws.
5. Test Operation: Gently open and close the door several times to check for smooth operation, proper alignment, and clearance. Adjust screws if necessary to achieve optimal performance.

Operating Instructions

Once installed, your McKinney Products MPB79 hinges are designed for reliable and smooth operation. Simply open and close the door as intended. The bearing mechanism ensures minimal friction, and the non-removable pin provides security by preventing unauthorized removal of the door from its frame when closed.

Maintenance

• Cleaning: Clean the hinges periodically with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the satin chrome finish.
• Lubrication: If the hinges begin to squeak or feel stiff, apply a small amount of silicone-based lubricant or a light machine oil to the hinge pin and bearing areas. Wipe off any excess lubricant.
• Tightening Screws: Periodically check all hinge screws for tightness. Loose screws can lead to door sagging or misalignment. Tighten any loose screws gently to avoid stripping the screw heads or wood.
