Key-Operated Push-Button Lock

This key-operated push-button lock is easy to install and convenient to use, and was developed specifically for aluminum profile doors and windows. It locks with a simple push and offers enhanced security when used in conjunction with a key. It is widely used in residential, commercial, and various aluminum profile door and window projects.

High-Quality Materials, Precision Craftsmanship

The lock body is made of high-strength zinc alloy through a single-piece die-casting process, resulting in a sturdy and robust structure that resists deformation and wear. The product has passed a durability test of 100,000 opening and closing cycles, ensuring stable and reliable performance even with long-term, frequent use, and offering a long service life. It is manufactured in strict accordance with the QB/T5338-2018 industry standard for door and window hardware, with all performance indicators meeting industry specifications. Surface finishes are customizable. The product has passed a 500-hour neutral salt spray test, demonstrating excellent weather resistance, corrosion resistance, and scratch and wear resistance. It withstands the erosion of complex outdoor environments—including sunlight, rain, and temperature fluctuations—and remains resistant to rust, fading, and surface scratches over long-term use, ensuring lasting stability in both appearance and performance.

Push-to-Lock Mechanism with Key-Only Unlocking

Featuring a push-to-lock latch mechanism, the window or door locks securely with a gentle press when closed; opening requires the use of the matching key, as there is no automatic unlocking function. The latch engages tightly and remains secure, preventing accidental springing open and providing excellent anti-theft protection. It also prevents children from opening the window or door on their own, comprehensively enhancing home security. Positioning tabs on both sides ensure precise alignment during installation, resulting in a more secure lock when engaged.

Easy Installation, High Compatibility

The product features standard mounting holes, making on-site assembly quick and effortless, effectively reducing assembly time for window and door manufacturers and lowering labor costs. It is compatible with various types of aluminum profile windows, including sliding and casement windows, and is suitable for residential, commercial, and commercial construction applications.

Stringent Quality Control, Reliable Performance

Every lock undergoes multiple rigorous professional tests before leaving the factory, including a 100,000-cycle opening and closing durability test and a 500-hour neutral salt spray corrosion resistance test. Manufactured in accordance with the QB/T5338-2018 standard for door and window hardware, these locks offer secure locking and long-lasting durability, making them the preferred choice for door and window manufacturers, hardware wholesalers, and project purchasers.
