Simple Dial Style Combination Lock Keyless Three Dial for UPVC Aluminum Doors

Simple Dial-Style Combination Lock
This dial-style combination lock for doors and windows features a keyless design with a three-dial structure. The combination is fully customizable and is compatible with UPVC and aluminum alloy profile doors and windows. It complies with the QB/T5338-2018 industry standard, is easy to install and operate, and is widely used for garden gates, balcony sliding doors, storage room doors, outdoor fence gates, and other applications.

Composite Metal Construction for Sturdy and Durable Craftsmanship
The lock body base is crafted from aluminum alloy, offering excellent compression resistance and resistance to deformation. The three combination dials are made of zinc alloy through a single-piece die-casting process, featuring clear, wear-resistant numeric markings that remain legible and operate smoothly even after repeated use over time. Surface treatment options support customer customization, allowing for various spray-painted or anodized finishes to match a wide range of door and window color schemes.

3-Digit Combination Dial, 10,000-Combination Security
Equipped with three independent zinc alloy combination dials, the lock offers up to 10,000 possible combinations. The combination can be freely changed or reset, eliminating concerns about lost keys or the hassle of carrying them, and enabling keyless access. The dials feature moderate resistance, ensuring smooth rotation without loosening, precise number alignment, and simple unlocking—making them easy to operate for both the elderly and children. The built-in latch engages firmly when locked, effectively resisting forced prying and enhancing the anti-theft security of doors and windows.

Compliant with Industry Standards, Universal Compatibility with Profiles
The product is manufactured in strict accordance with the QB/T5338-2018 standard for door and window hardware locks, ensuring consistent quality and compliance. Compatible with the two major types of door and window profiles—UPVC and aluminum alloy—it suits a variety of door types, including sliding doors, hinged doors, courtyard gate doors, and storage room doors. The base features pre-drilled standard mounting screw holes, making drilling simple and installation straightforward, saving time and effort for door and window manufacturers during on-site assembly.

Keyless Convenience for Multiple Scenarios
By eliminating the traditional key mechanism, you no longer need to carry a key when leaving home, making daily ventilation and temporary access more hassle-free. Passcodes can be changed periodically, offering greater flexibility for use in rental properties, retail spaces, and courtyards. The lock body features a sleek, compact design that takes up minimal space and can be installed on both indoor and outdoor doors and windows. With excellent moisture-proof and rust-resistant properties, it remains reliable and free from jamming or malfunction even during long-term outdoor use.
