Emtek Tuscany Grip by Grip Handleset is Available in the Following Functions
Single Cylinder Handleset Emtek single cylinder handlesets are locked/unlocked with a key from the exterior and locked/unlocked from the inside of the home with a thumbturn. Single cylinder handleset are by far the most popular function of handle set. Double Cylinder Handleset
Emtek double cylinder handlesets have a keyed lock on both sides of the handleset. This means that to exit or enter the door you must have a key to unlock the door. Some people use double cylinder handlesets on glass doors where they are concerned that someone may be able to break the glass and unlock the door from the inside. The disadvantage of using a double cylinder handleset is that in the event of an emergency you would have to locate the key to unlock the door and get out of the building. For this reason we recommend the single cylinder handleset for most applications.
Dummy Handleset
If you have a double front door where one side is generally inactive while the other is always active, you will need a combination of two handle sets. For the active side, you'll need a single or double cylinder handleset. For the inactive door, you'll want to order a dummy handleset. This gives you the look of a complete working set, but doesn't have all of the mechanisms - perfect for an inactive door.
Add On: Emtek Interconnect device
Emtek offers an interconnect device as an available option for their active handlesets. The interconnect device connects the interior lever or knob with the deadbolt on an emtek handleset. When you turn the knob or lever the interconnect device retracts the deadbolt simultaneously to unlock the door. This is just an added convenience that is available, but not required.
