Introduction

Emtek C8056CK-US15 Crystal Series Diamond Crystal Grade 2 Knobset

Diamond Crystal Knob by Emtek Crystal Knobset Series

TheEmtek Diamond Crystalis 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.

TheCrystal Collection’sknob / 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.
