This Door Patch Lock is a semi-lock mechanism for glass door systems, primarily used to secure the door leaf and control the switch. It is commonly found on frameless glass doors, display doors, and office partition doors. Made of high-quality stainless steel (SUS304 or SUS316), it offers excellent corrosion and wear resistance. Its compact design features precision-rounded corners for a smooth, visually harmonious appearance.

High-Strength Construction

The Door Patch Lock is made of SUS304 or SUS316 stainless steel, boasting a tensile strength of 520 MPa, providing exceptional structural support. The lock body undergoes CNC precision machining, achieving a flatness tolerance of less than 0.05 mm. This ensures a tight fit against the glass during installation, preventing loosening or deformation with frequent use and maintaining stable performance over time.

Precision-Processed Lock Bolt

The bolt is made from high-hardness stainless steel bar stock, polished and hardened to a hardness of HRC 38–42. Tests show that the bolt remains flexible after 200,000 opening and closing cycles, with a friction loss rate of less than 0.5%.

Excellent Corrosion Resistance

This product has passed a 240-hour salt spray test and meets ASTM B117 corrosion resistance standards, ensuring long-term use in high-humidity, coastal, and moisture-rich environments. The surface protective film effectively resists corrosion from acids, alkalis, and detergents, maintaining its metallic luster over time.

High-Precision Fit

A 0.02mm gap design between the lock body, cover plate, and fixing screws ensures a perfect fit against the glass surface after installation, preventing loosening and gap noise. This precise fit ensures a stable closing and a tight seal.

Strong Installation Compatibility

Compatible with glass thicknesses of 8 to 12 mm, with an installation tolerance of ±0.5 mm. No deep drilling is required for fast installation, reducing stress concentration on the glass and improving installation safety and efficiency.

Office Partition Systems

In modern office spaces, Door Patch Locks are often used to secure glass partition doors. Their high-precision latch mechanism ensures a tight closure, preventing wiggle and shifting, maintaining privacy and soundproofing in conference rooms and individual workspaces. The lock body features a fingerprint-resistant brushed finish, ensuring it stays clean and tidy even with frequent use.

Home Glass Doors

In the home, Door Patch Locks are suitable for glass doors in areas such as balconies, kitchens, and shower rooms. They offer smooth closing, no metallic creaking, and smooth, quiet operation. Their minimalist appearance blends seamlessly with modern home styling. They are moisture-resistant and rust-resistant, offering low maintenance. Even in humid environments, they resist deformation and discoloration for extended use, providing a secure and durable locking solution for the home.

Exhibition and Art Spaces

Using Door Patch Locks in art galleries or exhibition halls ensures secure closure. Their concealed design minimizes visual distractions, maintaining a clean and aesthetically pleasing display area. Their precision-polished surface seamlessly blends in with glass display cases, creating a sophisticated, modern artistic atmosphere. Its wear-resistant construction withstands frequent opening and closing cycles, ensuring reliable operation during exhibitions.

Public Building Entrances

Installing a Door Patch Lock at the glass door entrance of an office building or shopping mall enhances security and durability. Its lock body can withstand over 100,000 opening and closing cycles, ensuring long-term reliable operation. Its precision construction prevents door rebound and misalignment, ensuring a smooth closing. Its brushed stainless steel finish resists fingerprints and scratches, maintaining a professional and clean appearance in public passageways.

1. What types of glass can the Door Patch Lock be installed on?

This product is highly compatible and suitable for tempered glass doors with a thickness of 8 to 12 mm. Its scientific structural design allows for secure installation without the need for additional drilling or welding brackets. The base and latch feature non-slip pads, creating a tight grip on the glass surface, ensuring a secure fit and preventing loosening or shifting. It is suitable for a variety of applications, including frameless doors, partition doors, and display doors.

2. Will it rust in humid environments or bathrooms?

No. The Door Patch Lock is made of SUS316 stainless steel, which offers excellent oxidation resistance and has passed a 240-hour salt spray corrosion test. It will not rust or discolor even in high humidity or frequent contact with moisture.

3. Is it suitable for commercial spaces with heavy use?

Yes. This product has passed a 200,000-cycle endurance test, ensuring it remains flexible and stable even in high-frequency use. The lock core is precision-engineered and wear-resistant, resisting friction wear caused by repeated operation. Its internal spring system uses a reinforced alloy, ensuring stable restoring force and preventing loosening or binding with long-term use.

4. Does installation require professional assistance?

We recommend an experienced installer. The Door Patch Lock's precision construction requires precise installation, ensuring the glass is perpendicular to the lock tongue and accurate alignment. Any installation deviation exceeding 0.5 mm may affect the closing effect. Professional installation ensures a perfect fit between the product and the glass, allowing for smoother opening and closing, extending the overall lifespan and ensuring safety.

5. How should it be maintained during daily use?

Daily maintenance is simple. It is recommended to wipe the surface with a soft, dry cloth every two weeks to maintain its gloss. Add a small amount of lubricant to the lock cylinder every three months to prevent dust accumulation and rotational problems. Avoid using acidic or chlorine-containing cleaners, as they may damage the passivation layer. In coastal or humid areas, regularly check the fixing screws and waterproof gasket to ensure the lock is secure and stable.
