Emtek Delaware Sideplate Lockset – Brass (Keyed & Non-Keyed)

The Emtek Delaware Sideplate Lockset blends timeless mid-Atlantic style with modern functionality, taking inspiration from Colonial, Cape Cod, and Dutch Colonial architectural details. Its tall, traditional backplate recreates the elegance of vintage mortise hardware, while using a simplified tubular system for installation and reliable daily use.

Offered in four refined configurations—7 1/8” Non-Keyed, 9” Non-Keyed, 3 5/8” C-to-C Keyed, and 5 1/2” C-to-C Keyed—the Delaware collection supports a full range of functions including Passage, Privacy, Dummy, Single Cylinder, and Double Cylinder. Each model can be paired with any Emtek brass knob or lever and is available in nine premium finishes, giving you complete flexibility to match your home’s style.

For advanced security options, the Delaware 5 1/2” C-to-C Keyed Sideplate exclusively supports the EMPowered™ Smart Lock (EMP2) upgrade, transforming the interior trim into a discreet smart-enabled system compatible with the Yale Access App.

What is a Sideplate?

A sideplate is a tall, decorative backplate that replaces the small rosette found on modern hardware. Emtek’s sideplates capture the look of antique mortise locks while using an easier tubular system, giving you vintage charm with modern convenience.

The Delaware collection is one of Emtek’s most iconic traditional styles, echoing early American architecture. Its classic silhouette pairs beautifully with glass knobs, brass knobs, and traditional lever designs, making it ideal for historic homes, restorations, and timeless interior themes.
