The Privacy Indicator Lock consists of a lock body, a deadbolt, an indicator panel on the outside of the door, an operating knob on the inside of the door, and a matching strike plate. It is a door lock specifically designed for use in restrooms, conference rooms, and other areas where a user's status needs to be displayed.

Intuitive Indication

The outside panel features a clear color indicator window, typically red for "in use" and blue or green for "vacant." This intuitive visual cue eliminates the inconvenience of knocking or accidentally pushing the door, enhancing privacy and managing space efficiency. The indicator window is approximately 23 mm wide and 12 mm high, making it clearly visible from a distance of two meters. The interior utilizes a transparent plastic sheeting combined with a metal frame to ensure long-term color stability and resist fading.

High-Strength Construction

The deadbolt is made of solid stainless steel, 8 mm thick, and has a lock retention force exceeding 500 N. The lock body is secured with four 4.5 mm screws and has a tensile strength that can withstand forces exceeding 30 kg, preventing loosening or dislodging. The knob and lock bolt utilize a metal latch mechanism, eliminating the wear issues associated with plastic components and ensuring a long-lasting service life of over 50,000 cycles.

Easy Installation

The Privacy Indicator Lock is compatible with doors with a thickness range of 28 to 40 mm, offering high versatility. The mounting hole is 16 mm in diameter, allowing for quick drilling with the aid of a positioning diagram. A 43 x 50 mm plate with three pre-set countersunk screw holes is included, eliminating the need for additional machining. Installation can be completed by a single person in under 5 minutes, significantly reducing construction time and maintenance costs, making it ideal for high-volume applications.

Public Restroom Doors

In public restrooms in large shopping malls, airports, or subway stations, the Privacy Indicator Lock provides intuitive "Open/Used" status indicators, effectively preventing the embarrassment of accidentally opening the door. Its corrosion resistance ensures long-term rust resistance in humid environments, and its emergency release function ensures safety in emergencies. Its 50,000-cycle lifespan fully meets daily needs in high-frequency use.

Hotel Bathrooms

Hotel bathrooms require not only privacy but also harmony with the overall decor. The brushed stainless steel finish harmonizes with modern hotel doors, and the indicator window provides a visual status indicator, allowing guests to easily determine whether the door is occupied. Easy installation makes it suitable for large-scale hotel projects. The silent and smooth opening and closing experience also provides enhanced comfort for guests of high-end hotels.

Hospital Public Restrooms

Hospital restrooms have extremely high hygiene and safety requirements. The SUS304 stainless steel Privacy Indicator Lock is corrosion-resistant and can withstand daily disinfection with chlorine-based detergents without damage. The indicator window helps medical staff quickly determine when a cubicle is occupied, improving crowd management efficiency. The emergency release design allows for quick intervention in emergencies, ensuring user safety, making it particularly suitable for the high-frequency use required in medical settings.
