It supports remote control, Tuya Wi-Fi remote unlock, Bluetooth unlock and fingerprint & PIN keypad options, covering every user’s individual needs.
1. Zinc-alloy strength & durability
WF-019 uses premium zinc alloy as the main material, offering outstanding physical properties:
- High strength & wear resistance: high hardness and strong impact resistance, effectively preventing forced entry
- Excellent corrosion resistance: special surface treatment adapts to all climates and gives long service life
- Precision die-casting: one-piece moulding ensures tight tolerances and smooth operation
- Beautiful & durable: available in silver, gold and blue-silver, retaining their look for years
Zinc alloy provides high structural strength plus good machinability, enabling the complex geometry required for invisible mounting.
2. Invisible design & space optimisation
WF-019 is completely hidden after installation, delivering unique space advantages:
- Maximum concealment: the lock body is fully embedded inside the door leaf; no hardware is visible from either side
- Space saving: no external protrusions keep the doorway clean and elegant
- Superior anti-theft performance: the hidden mount defeats both technical picking and brute-force attacks
- Wide adaptability: suits wooden, metal or composite doors and installs flexibly
Invisible design boosts security while preserving the architectural aesthetic—perfect for modern minimalist décor.
