Interior Door Lock With delicate beveling and a transitional profile, the Ellington series balances new and old for a polished look. Perfect for a traditional Cape Cod home or an updated Tudor, the Ellington showcases the best of both stylistic worlds with ease. Select from keyed, passage, privacy, and dummy (pair) functionality.

Commonly used for bedrooms and bathrooms. Passage: Latches but does not lock—used for rooms where privacy isn’t needed, like hallways or closets. Dummy: Decorative handles that don’t turn or latch. Used on fixed doors like pantry or French doors. Measurements: Backset Length (distance from center of lock to edge of door): adjustable between 2 3/8" and 2 3/4") Door Thickness: Fits standard 1 3/8" to 1 3/4" thick doors
