Installation Process

Proper installation is critical to the performance and longevity of full mortise continuous geared aluminum hinges. The following steps provide a comprehensive guide to ensure correct installation:

1. Preparing the Frame:

· Positioning the Hinge: With the hinge in the open position, use a shim to position the top end of the hinge 1/8" (3.2mm) below the header for door clearance.

· Marking and Drilling Holes: Accurately mark or center punch the hole locations. Drill the holes using a #13 (.185) or 3/16" (.188) drill bit for metal doors, or a 5/32" (.156) drill bit for wood doors.

· Cutting Adjustments: If the hinge needs to be shortened, cut only one end using a hacksaw. Ensure the hinge is in a closed position with the cap up or on its side. Reinstall the cap on the hinge after cutting to ensure smooth operation.

2. Attaching the Hinge to the Door:

· Aligning the Hinge: Place the door leaf on the door, ensuring it is aligned along the full length of the door edge.

· Marking and Drilling: Mark or center punch, and then drill the holes.

· Fastening the Hinge: Attach the hinge to the door using the provided fasteners. For metal doors, use #12-24 flathead screws for both leaves. For wood doors, use #12-24 flathead screws in the frame and #12 x 1-1/2" flathead wood screws in the door.

3. Attaching the Door to the Frame:

· Positioning the Door: With the door at 90 degrees to the frame, align it with the top end screw hole.

· Securing the Door: Install one screw at the top to hold the door in place, then remove the wedge and install the remaining screws.

· Checking Alignment: Ensure the door swings properly and that there is adequate clearance to prevent binding.

Clearance Requirements

Ensuring the correct clearance is crucial for the smooth operation of full mortise continuous geared aluminum hinges. The clearance requirements vary depending on the type of door and its edge profile:

1. Single Doors (Square Edged):

· Hinge clearance: 5/16" (7.9mm)

· Lockside clearance: 1/8" (3.2mm)

· Clearance for irregularities: 1/32" (0.8mm)

· Total Clearance Required: 15/32" (11.9mm)

2. Single Doors (Beveled Edged):

· Hinge clearance: 5/16" (7.9mm)

· Lockside clearance: 1/8" (3.2mm)

· Beveled edged clearance: 1/32" (0.8mm)

· Clearance for irregularities: 1/32" (0.8mm)

· Total Clearance Required**: 1/2" (12.7mm)

3. Double Doors (Square Edged):

· First hinge clearance: 5/16" (7.9mm)

· First clearance for irregularities: 1/32" (0.8mm)

· First beveled edge clearance: 1/32" (0.8mm)

· Edge to edge clearance: 3/16" (4.8mm)

· Second hinge clearance: 5/16" (7.9mm)

· Second beveled edge clearance: 1/32" (0.8mm)

· Second clearance for irregularities: 1/32" (0.8mm)

· Total Clearance Required: 15/16" (23.8mm)

Reinforcements and Additional Considerations

For doors that are extremely heavy or extra-wide, reinforcing the hinge with Riv-Nuts is recommended. This reinforcement is particularly crucial for doors exceeding 450 pounds (204 kg). Riv-Nuts provide additional support and ensure the hinge remains securely fastened under heavy loads.

1. Pairs of Doors with Mullions:

· If the mullion is between the doors, treat it as a single door installation.

· If the mullion is behind the doors, treat it as a double door installation.

2. Grouted/Flushed-In Frames:

· Ensure a mudguard is installed behind the frame for ease of installation.

· Avoid using self-drilling, thread-forming screws with grouted steel frames that lack a mudguard.

Detailed Installation Tips and Best Practices

1. Pre-Installation Checks:

· Verify that the door and frame are plumb, level, and square. Any misalignment can affect the performance of the hinge.

· Ensure that all materials and tools required for installation are on hand to prevent delays and ensure a smooth installation process.

2. Cutting Adjustments:

· When shortening the hinge, it is crucial to cut only one end and to use a hacksaw or similar tool to ensure a clean cut.

· The cut end should be reinstalled with the cap to maintain the integrity of the hinge and ensure that it operates correctly.

3. Using Shims for Alignment:

· Shims can be used during installation to ensure that the hinge is positioned correctly and to provide the necessary clearance between the door and frame.

· This helps to prevent binding and ensures smooth operation.

4. Secure Fastening:

· Ensure all fasteners are properly tightened, but avoid over-tightening, which can strip the screws or damage the hinge.

· Use the correct drill bits for metal or wood doors as specified to ensure that the holes are properly sized and aligned.

5. Regular Maintenance:

· Periodic inspection and maintenance are recommended to ensure the longevity and performance of the hinges.

· Check for any signs of wear or damage, and reapply lubricant if necessary to maintain smooth operation.

Comparison of Full Mortise Hinges with Other Types of Hinges

Full Surface vs. Full Mortise Hinges

· Full Surface Hinges: These are mounted on the surface of the door and frame, making installation easier and providing a higher degree of stability. They are visible when the door is closed, which might be a consideration for aesthetics.

· Full Mortise Hinges: These are installed within the mortise cutout in the door and frame, offering a more concealed look but requiring precise installation. They provide a cleaner, more streamlined appearance as they are not visible when the door is closed.

Full Surface vs. Swing Clear Hinges

· Full Surface Hinges: Provide a simple installation process and ensure the door operates smoothly without requiring additional space. They are generally easier to install and maintain.

· Swing Clear Hinges: Designed to swing the door completely clear of the opening when open, making them ideal for applications requiring maximum clearance, such as ADA compliance or moving large objects through doorways.

 

Full Mortise vs. Half Mortise Hinges

· Full Mortise Hinges: Installed into cutouts in both the door and frame, providing a flush fit that is aesthetically pleasing and secure. They require precise mortising during installation.

· Half Mortise Hinges: These are installed with one leaf mounted on the surface of the frame and the other leaf in a mortise cutout on the door. This offers a compromise between the concealed look of full mortise and the easier installation of surface-mounted hinges.

Full Mortise vs. Half Surface Hinges

· Full Mortise Hinges: Require mortising in both the door and the frame, providing a concealed and secure fit. Ideal for high-traffic and heavy-duty applications where aesthetics are also important.

· Half Surface Hinges: One leaf is mounted on the surface of the door, and the other leaf is mortised into the frame. This allows for easier installation on the door while still providing some of the benefits of a concealed hinge.

Full Mortise vs. Butt Hinges

· Full Mortise Hinges: Offer a more concealed look with the hinge leaves set into the door and frame, requiring precise mortising. Suitable for high-traffic doors where aesthetics are important.

· Butt Hinges: Typically smaller and easier to install, with both leaves mounted on the surface. They are more visible but are often used for interior doors where heavy-duty performance is not as critical.

Full Mortise vs. Continuous Hinges

· Full Mortise Hinges: Installed in cutouts in the door and frame, offering a concealed and secure fit. Best suited for heavy-duty applications and doors where aesthetics are a priority.

· Continuous Hinges: Run the entire length of the door, distributing weight more evenly and providing increased support and durability. Ideal for high-traffic areas and doors subject to constant use, though they are more visible than full mortise hinges.
