#1 for performance and design

Schlage D-Series

Schlage D-Series knobs are built to tough manufacturing standards that ensure a long life with smooth performance. With finishes to fit your building design, and a choice of styles, the D-Series is one of the toughest knobs we make.


We don’t compromise on security.

The safety and security of your clients’ buildings is something we take very seriously. That’s why every Schlage lock and deadbolt undergoes intensive testing to determine its ANSI grade level:


• Cycle tests
• Resistance tests
• Door impact tests
• Warped door tests
• Bolt strength tests
