Key Points
🔒 Premium Zinc Alloy · Corrosion and Rust Resistance
The lock body is forged from premium zinc alloy and undergoes multiple anti-rust treatments. It is waterproof and moisture-resistant, ensuring it stays as good as new even when installed in humid environments such as bathrooms, kitchens, and balconies. The metal has a cool, solid feel—without the brittleness of plastic—and features rounded, chamfered edges, making it safe to use even in homes with small children.
🚪 Universal for Double Doors · Opens Left or Right
Designed specifically for double-door cabinets, it’s also compatible with single doors, sliding doors, drawers, file cabinets, refrigerator doors, and more. The left/right-handed design ensures easy installation and use regardless of which direction the cabinet doors open.
🔧 Two Installation Methods · Choose Between Drilling or Drill-Free
Adhesive Installation (Recommended): No drilling required; won’t damage the cabinet surface or leave marks. Clean the installation surface, apply the included adhesive, press firmly into place, and let it set for 48 hours to achieve optimal adhesion.
Screw Installation: Includes mounting screws, suitable for situations requiring stronger hold (such as high-frequency use or heavy-duty cabinet doors).
🔐 3-Digit Combination · 1,000 Combinations · Reset Anytime
The initial combination is 0-0-0. With 1,000 possible combinations, you can enjoy greater peace of mind against theft. The combination can be changed freely at any time, so there’s no need to replace the lock when moving to a new home. The purely mechanical design requires no batteries, so you’ll never have to worry about it failing due to a power outage.
🛡️ Hidden Screw Holes + Upgraded Hook Lock · Enhanced Security
The concealed screw hole design hides the screw locations from view; the upgraded hook lock mechanism ensures the lock cannot be pried open with tools from the outside, even if there is a slight gap under the door. The recessed installation system guarantees enhanced security.
🌙 Glow-in-the-Dark Option Available · Concealed Screw Holes
The glow-in-the-dark version makes it easy to locate the lock in the dark, while the concealed screw hole design ensures a more aesthetically pleasing installation.
