The Armstrong SDDF-002 is an embedded fingerprint smart lock specifically engineered for sliding doors and hidden doors. It seamlessly blends minimalist aesthetics with practical utility, featuring an external reader that sits flush with the door surface and an internal manual knob for easy exit. This lock is the ideal solution for achieving a clean, handle-less look for residential, office, or retail sliding door systems.

The SDDF-002 overcomes the design challenges of traditional sliding door hardware. Its recessed design allows the door to align perfectly with the wall, eliminating bulky external housings. While the exterior offers high-precision fingerprint access, the interior integrates a sleek circular knob for effortless manual operation. With support for up to 20 fingerprints, a special mechanical override tool, and a USB-C emergency power port, it provides unparalleled security and peace of mind.
