DOOR HARDWARE - Doorsets - Function

Q: How do I determine which function I need for my conversion/tubular door set?

A: Most conversion/tubular door sets are offered with four function options: passage (for non-locking doors), privacy (for bath and bedroom doors), double dummy (for non-latching closet and double doors) and single dummy (for non-latching doors).  See chart below for more information about each door set function.
