Diamond Crystal Privacy Knobset with Brass Rosette

Emtek's privacy knobsets use traditional American locks and latches complete with a variety of trim styles; handcrafted from authentic materials. The knobset is operated by a knob from both the interior and exterior. With the privacy function; the door is locked via a push pin on the interior. The exterior has an emergency release hole that allows the door to be unlocked if necessary. Uncompromisingly rugged and beautifully crafted; these locks are suitable for the very finest homes.

These stunning crystal knobs are reproductions of early American designs. Each knob is hand polished and fitted to a sturdy and attractive brass rosette. The latches are heavy-duty die cast construction; with strong internal springs; solid brass nose bolts; and sintered metal cams. A plastic bushing located in the joint between the handle and the rosette ensures a friction-free wear surface; preventing metal from bearing on metal and providing smooth; long-lasting operation. Handles are positively connected to rosettes with a permanent clip. Each has a set screw which eliminates 'handle wobble' when tightened. Emtek's threaded tubes are machined brass to ensure good threads and prevent corrosion.
