What You Should Know About the Schlage Plymouth Knob:

Note: Schlage entrance locks have a turn button on the inside and are designed to stay locked unless turn button lock is disengaged by the user. Schlage privacy locks have a push button lock on the interior which is disengaged when the knob or lever is turned from the inside.

Finish Note: Oil Rubbed Bronze and Aged Bronze are quite similar. We are noticing more people prefer the Aged Bronze because it has more of a glossy finish with a rubbed look. The Oil Rubbed Bronze is more of a solid matte brown color.

Schlage Door Knob Functions

Schlage F51 Entrance Knob Function F51A Entrance. The F1A Entrance function is the most popular type of entrance lock. This lock is unlocked by key on the outside or by turning the door knob on the inside. The inside knob is always unlocked, so you can exit the house without unlocking the knob. This lock function is considered safer because you can exit the house quickly by just turning the knob. The inside is locked by push button. The button is automatically released when the inside knob is turned so you won't lock yourself out. Push in the lock button on your way out and the door will be locked behind you.
Schlage Storeroom Knob Function F80 Storeroom. A storeroom lock is typically used on an outside storage closet or storage room. This lock has a fixed knob on the exterior and always remains locked. The only way to unlock the door is with a key. The inside knob has no thumbturn and always remains unlocked.
Schlage passage knob function F10 Passage knob sets do not lock. They are generally used for hall or closet doors where a lock is not required. Sometimes passage knobs are used along with a deadbolt for a locking door. Passage knobs are suitable for interior or exterior use
Schlage F40 Privacy knob function

F40 Privacy door knobs are generally used on bedrooms and bathrooms. Privacy knobs lock, but it is not a keyed security lock. Schlage privacy knobs can be locked from the inside with a turn button in the knob. Can be unlocked from the outside with a generic unlocking tool.

Schlage F170 Dummy knob Function

F170 Dummy door knobs are just one knob that mounts to the door with a mounting bracket. To use a dummy knob your door must not have the 2-1/8" hole drilled as you would for a regular knob set. Dummy knobs are the perfect solution for ball catch doors or other applications where a latch is not needed, but the look of a doorknob is desired.

All lock functions include all the needed mounting hardware. Entrance, passage and privacy knob sets are full sets and include knobs for both sides of the door, latch, 3-way faceplate, strikeplate and mounting screws

Dummy knobs are sold as single knob with rosette and mounting bracket with screws. No latch, strike, or faceplates are included with the dummy function.

Passage, Privacy, and Dummy knobs are non-keyed

Looks nice. We got the aged bronze finish. One of the few door handles we could find that had the option of a 5" backset. However, sometimes the inside part of the door handle pops off when I'm trying top open the door.

A satisfactory doorknob
Bought this to replace a less than 5 years old Kwikset with 5" backstop. The design of the bolt mechanism on the Schlage has a more robust shape than the Kwikset, which has a crescent knife edge design that quickly wears down and the bolt doesn't retract completely anymore, trapping you in your house.
