Knoxville Style Brass Modern Single Cylinder Deadbolt Emtek's single cylinder deadbolts use traditional American locks complete with a variety of trim styles, handcrafted from authentic materials. The deadbolt is operated by a key from the exterior, and a thumbturn from the interior. Uncompromisingly rugged and beautifully crafted, these locks are suitable for the very finest homes. The Brass Modern Collection's 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.
