The Glass Door Patch Lock is a lock designed specifically for frameless glass door systems, ensuring secure closure and protection. Made of high-strength stainless steel (SUS304 or SUS316), it offers excellent corrosion resistance and long-term durability. The lock body features a simple, square design with a satin brushed or polished finish, creating a refined metallic texture that blends seamlessly with modern glass door structures. Flexible installation options ensure the glass door's transparent appearance, while offering smooth closing and easy unlocking, providing a quiet and seamless user experience.

High-Strength Construction

The Glass Door Patch Lock is constructed from SUS316 stainless steel, boasting a tensile strength of up to 520 MPa, ensuring stability under long-term loads and high-frequency opening and closing. The precision-milled edges of the lock body ensure a tight fit, effectively preventing loosening and deformation. It is suitable for large glass doors and can withstand door weights exceeding 70 kg.

Precision Lock Cylinder Design

The lock cylinder is manufactured from high-precision nickel-plated copper alloy, with internal structure accurate to 0.02 mm, ensuring smooth rotation and secure engagement of the bolt. The cylinder's rotational resistance is less than 1.2 N·m, making opening smoother and easier. It also offers pry and drill resistance, effectively enhancing the overall security of glass doors.

Corrosion Resistance

After a 240-hour salt spray test, the product showed no visible corrosion spots on the surface, complying with ASTM B117 standards. Whether exposed to coastal areas, high humidity, or frequent cleaning in commercial spaces, it maintains its stable appearance and mechanical properties, without rust or metal fatigue.

Sealing and Quieting Effect

The lock incorporates a wear-resistant silicone gasket that reduces metal-to-metal noise when the door is closed, keeping the average noise level below 38 decibels. The gasket also enhances the airtightness of the door gap, preventing dust and moisture from entering, and extending the overall life of the glass door system.

Exquisite Craftsmanship

Adopting a satin brushed or polished finish, the surface roughness Ra ≤ 0.8μm provides a smooth touch. High-precision machining ensures even transitions between corners and edges, resulting in soft, non-glare light reflection. It blends seamlessly with glass, aluminum alloy, and stainless steel door frames, enhancing the overall quality of the space.

Strong Installation Compatibility

The standardized design accommodates glass thicknesses ranging from 8 to 12 mm, with an installation tolerance of ±0.5 mm. Installation is completed without deep drilling or the need for additional fasteners, improving installation efficiency and reducing the risk of stress concentration on the glass structure.

Commercial Office Spaces

In modern offices, the Glass Door Patch Lock is used on frameless glass partition door systems, ensuring secure closure and enhancing privacy. Its silent mechanism effectively reduces opening and closing noise, creating a more comfortable experience for meetings and focused work.

Shopping Malls and Showrooms

When used on glass doors in shopping mall display areas, jewelry cabinets, or high-end showrooms, the Glass Door Patch Lock provides secure locking to prevent unauthorized opening while maintaining the transparency of the glass door, adding a sense of class and luxury to the display.

Hotels and Clubs

When used in hotel lobbies, VIP rooms, or bathrooms, this lock is moisture-resistant and oxidation-resistant, maintaining a polished finish over time. Its smooth opening and closing mechanism is convenient for guests, balancing safety and comfort, meeting the standards of high-end hotel facilities.

Medical and Laboratory Environments

This Glass Door Patch Lock is widely used on glass partition doors in hospitals, testing centers, and laboratories. Made of SUS316 stainless steel, it withstands corrosion from disinfectants, ensuring a tight seal and secure isolation. Its easy-clean design facilitates maintaining high hygiene standards.

High-End Residential Spaces

When used on balcony, study, or bathroom glass doors, this product offers a simple, modern appearance that blends seamlessly with the interior design. The smooth locking mechanism provides a secure and quiet experience, enhancing the overall quality of your home.

1. What thickness of glass is this glass door lock compatible with?

The Glass Door Patch Lock is suitable for tempered glass doors with a thickness between 8mm and 12mm. Installation requires no extensive processing of the glass, effectively preserving its integrity and security. Its standardized design makes it compatible with most frameless glass door systems on the market, suitable for single-door, double-door, and fixed-glass configurations.

2. Does installation require a professional?

Although this lock is relatively easy to install, it is recommended that it be performed by a professional installer. Because glass door installation requires precise leveling and lock cylinder alignment, installation tolerances should not exceed 0.5mm. Professional installation ensures even force distribution on the lock body, preventing misalignment that could cause leaks or latch jamming.

3. Will the lock rust in humid environments?

No. Made of SUS304 or SUS316 stainless steel, it undergoes a passivated and precision-polished surface treatment, and is salt spray resistant for over 240 hours. Even when used in bathrooms, coastal areas, or high-humidity environments, the surface remains smooth and rust-free.

4. How should daily maintenance be performed?

It is recommended to wipe the surface with a neutral detergent every three months and add a small amount of lubricant to the lock cylinder to maintain smooth operation. For doors in public places or those used frequently, the screws should be checked every six months to prevent loosening that could affect the door's closure.

5. Can this lock be used with other door control systems?

Yes. The Glass Door Patch Lock is compatible with a variety of floor spring, upper clamp, and door closer systems. When combined with hinges and frames, it can achieve one-way or two-way opening. It is suitable for a variety of glass door systems, such as offices, shops, hotels, and exhibition halls, ensuring overall security and structural harmony.
