What comes with the Emtek Square Crystal Knob?

Passage and privacy sets will come with knobs and rosettes for both sides of the door, along with a latch, strike and faceplates and mounting screws required.

Questions and Answers

Question hey i want to know if the dummy emtek crystal knob w modern disk square rosette in polished chrome comes with two dummy knobs...i need it for double door on each door ?
Asked by: tal ben-zaken - 12/24/2018
Question Yes these are sold as double dummies (dummy pair). So two knobs and rosettes surface mounted. So for one double closet door you would order one double dummy pair, and you would have a single knob for each door. Answer provided by:  Jake (12/24/2018)
