Concealed Top-and-Bottom Latch

This concealed top-and-bottom latch is a hidden locking accessory designed specifically for double doors and parent-child door sets. It features a zinc alloy faceplate paired with a galvanized steel latch bolt, which is recessed into the side of the door panel for hidden installation.

Premium Materials & Construction

The main body of the latch panel is made of high-density zinc alloy through a single-piece die-casting process. Its compact structure ensures high rigidity and excellent impact resistance and wear resistance, making it resistant to deformation, cracking, or loosening even after long-term, repeated opening and closing.

The surface features a matte black electrostatic spray coating with strong adhesion, providing scratch resistance and oxidation resistance. The matching latch rods are precision-crafted from galvanized steel, offering ample strength and excellent rust resistance.

Advanced Locking Mechanism

Featuring a concealed top-and-bottom lock structure, the upper and lower bolts are installed at the top and bottom of the door leaf. Turning the built-in knob causes the bolts to extend and retract simultaneously, achieving dual-direction locking between the door leaf, door frame, and floor.

The even distribution of force across the locking points effectively prevents door leaf wobbling and prying from external forces, significantly enhancing the door's airtightness and anti-theft performance.

Ergonomic Design & Installation

The recessed knob design conforms to the natural curve of the finger, ensuring smooth, jam-free operation. The locking feedback is clear and crisp, making daily opening and closing effortless.

Featuring a recessed, concealed structure, the unit sits flush with the side of the door panel after installation, with no protruding parts. It uses industry-standard installation dimensions, making it compatible with a wide range of door types.

Applications

Double-leaf entry doors
Master-and-slave security doors
Double-leaf balcony swing doors
Interior double doors
Bathroom double doors
