Emtek's Delaware Sideplate Lockset pairs a taller sideplate backplate — reminiscent of a vintage mortise box lock — with your choice of Emtek brass knob or lever. Choose size and function below, then add your knob/lever and finish. Sold as a complete set with latch, strike plate and dust box.

Functions: Passage, Privacy, Single/Double Cylinder Keyed, Dummy, plus EMPowered 2 smart lock on 5-1/2" keyed
Schlage® C keyway; 2-3/8" backset standard (2-3/4" on request)
Door prep: most sizes use a standard 2-1/8" bore — but the 3-5/8" C-to-C keyed configuration is NOT a standard door prep and requires a custom bore. Confirm your door prep before ordering.
Handing required for leversets; 28° rotation latch for levers, standard for knobs
Knob/lever selected separately — pairs with any Emtek brass knob or lever
Unlacquered Brass (US3NL) available at a $20 list upcharge
