The Occupied Door Lock consists of a lock body, a circular external indicator panel, a knob, and a striker. The exterior is crafted from SUS304 stainless steel with a brushed or mirrored finish. The indicator panel is 60 mm in diameter, while the lock body is 82 mm long, achieving a moderate overall thickness. Red and green display windows on the exterior clearly indicate "in use" and "idle." The lock is easy to operate, compact, and robust.

Durable and Sturdy

The lock body is precision-cast from SUS304 stainless steel, 2 mm thick. The lock bolt is a solid cylindrical structure with a diameter of 12 mm and can withstand shocks exceeding 400 N. The mounting hole uses a standard 4 mm countersunk hole and securely fastens to the door with stainless steel screws. The knob, approximately 20 mm in diameter, is designed to fit comfortably, making it easy for even children and the elderly to operate. The entire Occupied Door Lock has been tested for 50,000 opening and closing cycles, ensuring long-term stability in high-use environments.

Corrosion Resistance

Due to its widespread use in restrooms and humid environments, the Occupied Door Lock features a brushed stainless steel exterior for superior corrosion resistance. It has been tested for over 240 hours in a neutral salt spray test, ensuring long-term rust-free use. For coastal or high-humidity locations, an optional enhanced electroplating version with a coating thickness of 8 to 12 microns further enhances weather resistance. The surface treatment is both fingerprint-resistant and stain-resistant, requiring only a damp cloth for daily cleaning to maintain a pristine finish, making maintenance easy.

Easy Installation

The Occupied Door Lock features a split-piece design with mounting holes aligned with standard cubicle door spacing, requiring no special tools. Stainless steel screws and installation instructions are included, allowing one person to install the lock in under 5 minutes. Suitable for doors with thicknesses ranging from 28 to 40 mm, it offers wide compatibility, allowing the lock to replace existing locks without modifying the door structure. For large-scale installations, such as restrooms in shopping malls or airports, this significantly reduces installation and maintenance costs.

The Occupied Door Lock's red and green indicator windows help customers quickly determine the status of a stall, reducing wait times and misunderstandings.

The emergency unlock function allows management to quickly respond to emergencies, enhancing safety.
