Emtek C8107CK-US3LFT Crystal Series Diamond Crystal Grade 2 Knobset
Diamond Crystal Knob by Emtek Crystal Knobset Series
The Emtek Diamond Crystal is a rugged and beautifully crafted knobset using traditional American 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.
The Crystal Collection's knob / lever handles are supported by springs mounted behind the rosettes and sideplates, which return the handles back to the rest position and prevent lever sag. The latches are heavy-duty die case 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 positvely 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.

CF Mechanism: Emtek's Concealed Fastener Mechanism (CF Mechanism) is an optional upgrade to your order and consists of concealed screws (no exposed screws). The chassis design of the CF Mechanism is spring-loaded on both sides and comes standard with the 28° Latch. The CF Mechanism is available for all Brass, Stainless Steel, Bronze and Crystal interior passage, privacy & dummy locksets.
28° Latch: The 28° Latch is available as an optional upgrade without the CF Mechanism. These latches are available for all our current brass, bronze, and wrought steel privacy, passage, and platesets. The 28° latches are an ergonomic alternative to standard latches, shortening the rotation required to turn the knob or lever. Please see "Related Items" above.
