The D Series provides heavy-duty performance for high-traffic applications in a knob design lock. Accessory options also allow lever use.

Schlage D Series cylindrical locks are knob-only locks built to survive in the toughest environments. The ANSI/BHMA Grade 1 rating allows the D Series to fit in applications like military barracks, back-of-house hospitality and repair/replace instances. Three knob styles and ten finishes make the Schlage D Series the perfect retrofit option.
