Details

Mounting Options:
Door hinges are designed for installation on the door edge and the corresponding frame. Placement and method depend on hinge type.

Tools You May Need

• Screwdriver (Phillips or flathead)
• Drill and drill bits
• Chisel (for mortising)
• Screws
• Tape measure and pencil
• Level or square
• Hammer and mallet

A. Mortise Hinges

Step 1: Mark Placement

Measure and mark hinge positions on the door edge. Standard placement is:

• Top hinge: 5–7 inches from the top of the door.
• Bottom hinge: 10–12 inches from the bottom.
• Third hinge (if used): centered between top and bottom.

Step 2: Mortise the Door and Frame

Trace the hinge outline. Chisel shallow recesses into the door edge and frame so the hinge leaf sits flush.

Step 3: Pre-Drill Screw Holes

Place the hinge in the mortise, mark screw locations, and drill pilot holes.

Step 4: Attach Hinges

Screw one leaf of each hinge to the door edge. Position the door in the frame and secure the other hinge leaf to the jamb.

Step 5: Test Door Swing

Open and close the door to ensure smooth movement. Adjust screws if necessary.

B. Concealed Hinges

Step 1: Mark and Cut Recess

Mark hinge placement on both the door edge and the frame. Use a router or chisel to cut recesses deep enough to house the concealed hinge body.

Step 2: Position and Pre-Drill

Insert the hinge body into the recess, align flush with the surface, and mark screw holes. Drill pilot holes.

Step 3: Attach Hinges

Secure the hinge body into both the door and the frame using provided screws. Ensure full seating for proper alignment.

Step 4: Adjust Alignment

Most concealed hinges include adjustment screws. Use these to fine-tune door alignment vertically and horizontally.

Step 5: Test Operation

Open and close the door fully to confirm smooth, quiet motion without rubbing or binding.

Important Tips

• Always mark hinge locations carefully before cutting or drilling.
• Mortising ensures hinges sit flush and the door closes properly.
• Use a level to check vertical alignment.
• For heavy doors, use at least three hinges.
• Periodically tighten screws to maintain performance.
