02MATERIALS
Built from solid zinc alloy
The body is constructed from solid zinc alloy, a material chosen for its density and resistance to the elements. A protective coating shields the metal from rust and tarnish, making it suitable for humid bathrooms or exposed outdoor gates. The finish remains polished over time, maintaining a clean aesthetic even under frequent use.

04DETAILS
A satisfying mechanical click
The U-shaped catch engages with a smooth rotary knob, producing a distinct, audible click that signals the door is fully secured. This tactile feedback provides immediate reassurance, replacing guesswork with certainty. The design prioritizes function, ensuring the mechanism feels robust rather than decorative.
05INSTALLATION
Simple alignment and screwing
Fitting the latch requires only basic tools: align the components, mark the positions, and drive the screws. There is no need for complex drilling into expensive wood or tile, making it a manageable project for most households. The process is straightforward, minimizing disruption to your home while adding a layer of security.
