Zinc Alloy Indicator Double Hook Sliding Door Lock

Indicator Double Hook Sliding Door Lock

This heavy-duty double hook sliding door lock with occupancy indicator is a professional hardware solution specially designed for wooden, aluminum and alloy sliding bathroom, bedroom and public restroom doors, widely applied in residential apartments, hotels, office buildings, shopping malls and commercial restroom projects.

Constructed with a solid lock body coated with iridescent galvanized anti-rust plating and a brushed stainless steel circular cover plate, the lock delivers outstanding corrosion resistance against humid bathroom environments and long-term daily abrasion. Its core design relies on a dual hook bolt mechanism, which provides far superior locking stability compared with traditional single-latch sliding locks. The two angled steel hooks firmly grip the strike plate on the door frame when locked, effectively preventing the door from being pried open or accidentally slid apart under external force, greatly boosting privacy and safety for occupied restrooms.

A prominent red-green visual occupancy indicator is embedded at the center of the round escutcheon, serving as a clear visual signal for people outside the door. Red means the room is occupied and locked from the inside, while green shows the compartment is vacant. This eliminates awkward knocks or accidental entry and is an essential feature for high-traffic public washrooms. The lock uses a simple turn knob for indoor locking and unlocking without a key, and it comes with an emergency release slot on the indicator core, allowing staff to manually unlock the door from the exterior with a flat screwdriver or coin in case of accidental locking inside, which avoids lockout emergencies.

The slim mortise lock body fits standard pre-cut grooves for sliding doors, making installation quick and compatible with most common sliding door thicknesses. The side mounting plate with preset screw holes enables stable fastening to the door edge without wobbling after years of frequent pushing and sliding. The brushed stainless steel finish matches most modern door trims and resists fingerprints and water stains perfectly.

This indicator double hook sliding lock balances durability, practicality and visual convenience. It solves the common flaws of conventional sliding door locks such as easy slippage and unclear occupancy status, making it a cost-effective, reliable choice for both new door installation and old lock replacement in wet, high-frequency usage areas.
