Product Overview

Continuous Geared Aluminum Full Surface Hinges by Zhejiang Cross Hardware are meticulously engineered to deliver superior performance and longevity. These hinges are perfect for environments where durability and reliable operation are paramount, such as schools, hospitals, office buildings, and industrial facilities. They are crafted from high-grade aluminum, providing excellent resistance to wear and tear, making them suitable for high-traffic areas.

Key Features:

1. Durability: Constructed from high-quality aluminum, these hinges are resistant to rust and corrosion, ensuring long-term use even in harsh environments.

2. Smooth Operation: The continuous geared mechanism allows for seamless, quiet operation, reducing wear on both the door and the frame.

3. Full Surface Mounting: This feature simplifies installation and enhances the stability of the door, making it a preferred choice for various applications.

Benefits of Continuous Geared Aluminum Full Surface Hinges

Enhanced Security: Continuous hinges run the full length of the door, providing better security compared to traditional hinges. This design makes it more difficult for intruders to tamper with or remove the door. Unlike traditional hinges, which can be pried apart or have their pins removed, continuous geared aluminum full surface hinges eliminate these vulnerabilities by distributing the load across the entire length of the door. This not only increases the door's resistance to forced entry but also ensures that the door remains securely attached to the frame under heavy use or impact.

Reduced Maintenance: The robust design of these hinges means they require less maintenance. The smooth operation reduces the wear and tear on the door and frame, leading to fewer repairs and replacements. Traditional hinges often suffer from alignment issues and sagging over time, especially under heavy usage. Continuous geared aluminum full surface hinges, however, maintain their alignment and functionality much longer due to their integrated gear mechanism and full-length support. This reduces the frequency of maintenance checks and the associated costs, making them a cost-effective choice in the long run.

Aesthetic Appeal: These hinges offer a clean, streamlined look that can enhance the overall appearance of the door system. They are available in various finishes to match different design preferences. The seamless design of continuous geared hinges eliminates the need for multiple visible hinge points, creating a more aesthetically pleasing door appearance. This can be particularly beneficial in commercial settings, such as offices and retail spaces, where the visual appeal of the door systems can contribute to the overall interior design. Available finishes include brushed aluminum, polished brass, and anodized colors, allowing for customization to fit any architectural style.

Longevity: Made from durable aluminum, these hinges are built to withstand heavy use and harsh conditions, providing a long-lasting solution for high-traffic areas. Aluminum is known for its corrosion-resistant properties, making these hinges suitable for environments exposed to moisture, chemicals, or extreme temperatures. This durability ensures that the hinges will not only last longer but also maintain their performance and appearance over time. The continuous gear mechanism also distributes the stress evenly along the door, reducing the likelihood of mechanical failure and extending the life of both the hinge and the door itself.

Detailed Installation Instructions

Proper installation is crucial for the optimal performance of continuous geared aluminum full surface hinges. The following steps outline the comprehensive process for installing full surface hinges KSCH001 and KSCH002.

I. Pre-Installation Preparations

Clearance Requirements:

For single and double doors, it is essential to calculate the clearance requirements accurately:

· Single Door: Frame Opening - Total Clearance Required = Net Door Width

· Double Door: Frame Opening - Total Clearance Required = Net Door Width Per Door

Clearance Details for Single Doors:

· Hinge Thickness: 0”

· Lock Side Clearance: 1/8” (3.2mm)

· Clearance for Irregularities: 1/16” (1.6mm)

· Total Clearance Required: 3/16” (4.8mm)

Clearance Details for Double Doors:

· First Hinge Thickness: 0”

· First Clearance for Irregularities: 1/16” (1.6mm)

· Edge to Edge Clearance: 3/16” (4.8mm)

· Second Hinge Thickness: 0”

· Second Clearance for Irregularities: 1/16” (1.6mm)

· Total Clearance Required: 5/16” (7.9mm)

II. Installation Process

1. Attaching the Hinge to the Frame:

· With the hinge in the open position, use a shim to position the top end of the hinge 1/8” below the header to allow for door clearance. This ensures that the door will have enough space to swing freely without scraping the floor or frame.

· Line up the hinge with the door side edge of the frame or your alignment line, ensuring no part of the hinge protrudes beyond the frame. This alignment is crucial for a smooth operation and aesthetic finish.

· Fasten the frame leaf at one top and one bottom hole using the #12-24 flathead screws provided. For wood frames, use the #12 x 1-1/2” wood screws and a 5/32” drill bit to pre-drill the holes. This helps prevent the wood from splitting and ensures a secure fit.

· Note: The frame leaf is mounted to the face of the frame using #12-24 x 1 1/16” flat head self-drill screws. These screws are designed to cut through the material without the need for pre-drilling, saving time and effort.

2. Preparing the Door:

· Attach the door leaf to the door through the locator holes using the panhead tek screws. These screws are designed to provide a strong, reliable hold.

· Optionally, all locator holes may be used for maximum stability and alignment precision.

· A #3 Phillips driver is required to secure the screws properly. This driver size ensures you can apply the necessary torque without stripping the screw heads.

· Remove shims and check door clearances. Occasionally, the door will sag slightly when shims are removed; adjust as needed to bring the door back into alignment. Ensuring the door is level and properly aligned will prevent operational issues.

· Locate and drill holes for the thru bolts in the door, marking the location of the thru bolt holes with a 3/8” drill. This step ensures the door and hinge components are securely connected.

· Note: The door leaf is provided with 1/4-20 x 1-1/4” (Screw + Post), which are designed for a secure and tight fit.

3. Attaching the Door:

· Attach the door with the top and bottom thru bolts, making any further adjustments on the frame leaf. Ensure the door is correctly aligned to avoid operational issues.

· Completely secure the frame leaf using the flathead screws. Mark and drill the remaining thru bolt holes in the door, and secure the door leaf with the thru bolts and 1/4-20 shoulder screws. This step ensures that the door is firmly attached and operates smoothly.

4. Installing Covers:

· Back out set screws installed in the side of the door cover. This allows for the cover to be positioned correctly.

· Line up the door or frame cover with the top end of the hinge. Starting at the top, apply pressure along the length of the cover, snapping it into place as you go down the hinge. This ensures a neat and professional appearance.

· Tighten the set screws securely with a 3/64” Allen wrench. For added security, apply a bead of construction or panel adhesive inside the door cover or over the thru bolt heads. This helps to prevent the cover from coming loose over time.

 

III. Additional Notes and Considerations

· KSCH001: Requires a minimum of 7/8” of frame face for mounting. If you have more than 7/8” frame face, mark an alignment line on the frame face from 1” up to 1-5/16” away from the center of the gap between the jamb and the door. This ensures proper positioning and operation.

· KSCH002: Requires re-templating existing overhead closers to match the swing clear pivot point of the hinge. If not re-templated, the door will only open to 70 degrees in a 90-degree opening. Proper templating ensures full range of motion.

· Reinforcing and Rivnuts: No reinforcing is necessary except on extremely high-frequency, extremely heavy, or extra-wide doors. Rivnuts are recommended in the frame when door weight exceeds 450 pounds (up to 650 pounds). Rivnuts provide additional strength and durability.

· Pairs of Doors with Mullions: If the mullion is between the doors, treat as a single door installation. If the mullion is behind the doors, treat as a double door installation. This consideration ensures proper installation technique for different door configurations.

· Grouted/Slushed-in Frames: For ease of installation, it is recommended that some sort of mudguard be installed behind the frame. Do not use self-drilling, thread-forming screws with grouted steel frames having no mudguard. If mudguards have not been used, carefully drill pilot holes through the frame and remove grout for screw clearance. Do not oversize holes in the frame. Proper preparation of grouted frames ensures secure fastening and avoids damage to the frame.
