The Armstrong SDDS-002 is a concealed RFID smart lock specifically engineered for wooden sliding and hidden doors. Featuring a handle-less exterior, it allows the door to blend seamlessly with the wall for a clean, minimalist aesthetic. With its 13.56MHz RFID sensing technology and a 60mm backset mortise lock, it is the premier choice for modern architectural designs that prioritize both security and style.
The SDDS-002 redefines furniture and door security by making hardware "invisible." By eliminating bulky external housings and protruding handles, it creates a comfortable visual flow between the door and the wall. The lock supports RFID card access from the outside and features an internal manual knob for instant exit. For total peace of mind, a specialized mechanical override tool is included to ensure access in any emergency.
