The Y004 Crescent Lock is a fundamental component of the Durable Door System philosophy. Beyond basic security, the curved blade is engineered to pull the sliding sashes closer together as it engages, significantly improving acoustic insulation and thermal efficiency.

Manufactured by Luoqi Hardware, the Y004 features a reinforced zinc alloy body and a high-tensile internal spring mechanism. This ensures that the handle remains crisp and responsive through thousands of cycles, preventing the common "handle sag" found in lower-tier Steel Window Accessories.

◈ Ergonomic Grip

The handle geometry is designed for intuitive use, providing a comfortable touchpoint that makes engaging Quality Door Fittings a seamless part of daily operation.

◈ Tamper-Proof Drive

Once engaged, the crescent blade sits behind the frame profile, making it extremely difficult to manipulate from the exterior—a hallmark of the Luoqi Hardware security standard.

Utilizing advanced surface treatment, the Y004 series is tested to 480 hours of salt spray exposure, ensuring long-term aesthetic and mechanical integrity in coastal environments.
