    Charmingly Colonial

    The Colonial Sideplate encapsulates the timeless charm of a bygone era with its vintage look. This longer escutcheon showcases a classic design reminiscent of colonial times, adding a touch of historical elegance to any door. Its subtle, stepped frame detail not only enhances the overall look but also pays homage to the sophistication and refinement associated with colonial architecture.

    What exactly is a "Sideplate"?

    Emtek's Sideplate styles are an alternative to a standard rosette. They offer a taller backplate option, akin in size and style to a vintage interior mortise box lock that is common in older homes. Our sideplate options are a modern take on that original inspiration-- not just in updated style but with a more contemporary tubular latch. They can be paired with any knob or lever style and are also offered with locking options, as keyed sideplate styles or as One Point and Two Point locks.

    Shown here with the Modern Sideplate in Flat Black and Select L-Square Knurled Lever in Satin Brass.
