What You Should Know About the Schlage Bell 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 F51 Entrance. The F1 entrance function is the most popular type of entrance lock. This lock is unlocked by key on the outside or thumbturn 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.
Schlage F54 Entrance function F54 Entrance. This entrance function is also keyed on the outside and thumbturn on the inside, but when the knobset is locked, the inside knob will not turn. The knob has to be unlocked before you can exit the house. Some people prefer this lock function because its hard to lock yourself out of the house since the lock has to be unlocked to leave.
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

door knob
Our door was an older one with a 5 inch, instead of the standard 3 inch back set. We were told we would not find one because they were old and no longer made. I found you on line and order and 2 days later it arrived at my door. Easy to install, looks great and works like a dream. Thank you.

Worked like a charm. Looks like it has always been there. Matches the original almost to a "T" Did not know the handle automatically unlocks the door every time you open the door causing the need to "always" re-lock the door. I suppose it is a feature to keep you from locking yourself out. If there is a tab or some cam you could install in the future as an override option, I think that would be appreciated, thereby removing the need to re-lock.

Question What's the difference from the F10? Thanks
Asked by: Robert Hackl - 11/30/2018
Question Hi,

With most hardware, the part numbers change based on the function of the lockset, the knob or lever style and the finish, among other things.

F10 is Schlages part number for a residential passage set
F40 is Privacy
F51 means "Keyed Entry"
F80 Storeroom
F17 Dummy

and on and on. Please give us a call if we can help you with anything else. 307-886-9449. Thanks Answer provided by:  Zach (11/30/2018)
