• Passage Function: Emtek's passage knobs and levers have no locking mechanism and is free turning on both the inside and outside. Many times passage knobs and levers are used on either a hallway or closet door where no security is necessary, but sometimes are used paired with a deadbolt for an entrance or back door.

• Solid Brass Trim: Many door hardware products are crafted from aluminum or plated steel, but the difference between these lesser metals and solid brass is noticeable the minute you hold them in your hands—solid brass is heavier, smoother, and naturally resists corrosion, making it the ideal material to construct high quality, reliable door hardware.

• Living Finishes: Oil Rubbed Bronze is a living finish. Over time it will change, revealing the subtle metallic accents beneath. This aging takes on the visual characteristics of a unit much older than it really is. Those looking for a vintage look should definitely give this finish some consideration.

• CF Mechanism: Emtek's proprietary CF Mechanism design incorporates a unique chassis design that significantly shortens the rotation and creates a more crisp and ergonomic function. This 28° latch mechanism comes standard with all units equipped with the CF Mechanism, affording a superior and robust operation.

• Concealed Screws: Emtek knobs and levers that feature the CF Mechanism install cleanly on both the interior and exterior of the door, completely concealing all screws required for the installation. All you'll ever see is the door and the hardware you've chosen for it—both seamlessly co-existing.
