Vintage-inspired door knobs can add warmth and period character, but the right choice depends on more than appearance. Check whether you need a privacy lock or a passage knob, and confirm that the hardware fits your door’s thickness and existing latch or mortise lock. These three options offer different looks and functions, from a simple non-locking brass knob to crystal glass and a privacy set.

CLCTK Antique Brass Privacy Knob for Bedrooms and Bathrooms
The CLCTK is a round, antique-brass-finish knob set with a privacy lock. Its traditional shape and arched rosette suit rooms where you want a classic look without the exposed crystal style. The knob is described as zinc alloy, which gives the set a solid metal construction.
A thumb button locks the door from the inside, and an Allen key can unlock it from the outside in an emergency. That makes this model a practical fit for a bedroom or bathroom, but it is not a keyed entry lock. The latch adjusts to either a 2⅜-inch or 2¾-inch backset and is listed for doors from 1⅜ to 1¾ inches thick.
Compared with the other choices here, this is the clearest option when privacy is the priority. Its main trade-off is that the conventional round design is less decorative than the crystal knob, and you should confirm your door measurements before ordering.
Pros:
- Privacy lock with an inside thumb button
- Emergency outside release using an Allen key
- Adjustable latch for two common backsets
- Traditional round shape and antique brass finish
Cons:
- Does not provide keyed security
- Door thickness and backset should be checked before installation
Verdict: Choose the CLCTK if you want a vintage-style brass look with a privacy lock for a bedroom or bathroom.
newliplace Crystal Glass Knob for Mortise Lock Doors
This one-pack knob pairs crystal glass with an antique brass finish. The transparent knob offers a more decorative, period-inspired look than the solid brass-finish options, making it a possible choice for updating an interior door while keeping an existing mortise lock.
The spindle measures 6.7 mm, and the included metal sleeve can increase it to 8 mm to fit more mortise-lock setups. The listing describes it as suitable for many mortise locks, not every lock, so check the spindle and lock dimensions before buying. The product is presented as a replacement knob, so make sure the existing lock mechanism is in usable condition and compatible.
Unlike the CLCTK privacy set, this product is not described as including a new privacy latch. It is also sold as one pack, so check how many knobs your door project requires. Its distinctive glass look is the main draw; the fit depends more heavily on your existing hardware than with a complete latch set.
Pros:
- Crystal glass knob with an antique brass finish
- Spindle sleeve included to accommodate two listed diameters
- Designed for updating interior mortise-style hardware
Cons:
- Compatibility depends on the existing mortise lock and spindle
- Sold as a one-pack knob, not a complete privacy latch set
Verdict: Consider the newliplace knob if you want a crystal-and-brass accent and have confirmed that your mortise lock will accept its spindle.
HIEMEY Antique Brass Passage Knob with a Square Design
The HIEMEY is a passage knob set with an antique brass finish and a square design. It operates a latch but does not lock, so it is intended for hall, closet, and other interior doors where privacy is not needed. Its geometric shape gives it a more modern edge than the round CLCTK knob.
The adjustable backset accommodates 2⅜-inch or 2¾-inch measurements, and the listed door-thickness range is 1⅜ to 1¾ inches. Those dimensions make it important to measure your door before installation. The product is described as a DIY install, though you will still need the right tools and compatible door preparation.
This is the most straightforward pick for a non-locking interior door. If you need a bathroom or bedroom lock, choose the CLCTK instead. If your priority is a crystal accent or compatibility with a mortise lock, the newliplace knob serves a different purpose.
Pros:
- Passage function suits halls and closets
- Adjustable backset for two common measurements
- Antique brass finish with a distinctive square design
- Listed for common interior door thicknesses
Cons:
- Does not lock
- Square styling may not match a fully traditional room
Verdict: Choose the HIEMEY for a non-locking hall or closet door if you like a cleaner, more geometric take on vintage brass hardware.
How to Choose Vintage Mid-Century Door Knobs
Decide whether the door needs to lock
Start with how you use the room. A bedroom or bathroom usually calls for a privacy function, such as the CLCTK’s inside thumb button. Hall and closet doors often need only a passage knob that turns a latch without locking. A decorative replacement knob for a mortise lock may rely on the lock already installed in the door, so check what is included before you buy.
Check the door thickness and backset
Measure the door thickness and the distance from the door edge to the center of the knob hole. That distance is the backset. The CLCTK and HIEMEY list adjustable backsets of 2⅜ or 2¾ inches and doors from 1⅜ to 1¾ inches thick. Compare those numbers with your door rather than assuming the hardware will fit.
Identify the existing lock mechanism
Many older doors use a mortise lock, which sits inside a pocket cut into the edge of the door. The newliplace knob is intended for mortise-style hardware and includes a spindle sleeve, but its fit still depends on your lock’s measurements. A standard latch set is not automatically a replacement for a mortise lock, so identify the mechanism before selecting a knob.
Choose a shape and finish that suit the room
Round knobs and antique brass finishes give a familiar, traditional look. Crystal glass adds a more noticeable decorative element, while the HIEMEY’s square design feels more geometric. Consider the other door hardware and fixtures in the room, and remember that product descriptions do not guarantee an exact finish match with existing items.
Consider the material and what the package replaces
The CLCTK description specifies a zinc alloy rosette, while the newliplace option pairs crystal knobs with an antique brass finish. Also check whether you are buying a complete latch set or a knob intended to work with existing hardware. The product details differ: the CLCTK includes an adjustable latch, the HIEMEY is a passage set, and the newliplace is a one-pack replacement knob for mortise-style setups.
Plan for installation
These products are described as suitable for do-it-yourself installation, but the work can vary with your door’s existing holes and lock type. Read the included instructions and verify the hardware dimensions before removing your current knob. If your door has unusual preparation or an older mechanism, you may need to keep or adapt the existing lock rather than use a standard latch set.
Frequently Asked Questions
Which of these knobs locks from the inside?
The CLCTK has a privacy function with an inside thumb button. The HIEMEY is a passage knob and does not lock. The newliplace knob is designed for use with a compatible mortise lock, so its function depends on the existing lock hardware.
Are all three options complete door knob sets?
No. The CLCTK is described with an adjustable latch, and the HIEMEY is a passage knob set. The newliplace product is listed as a one-pack replacement knob intended for interior mortise-style locks, so check the package details and your existing hardware.
Will these fit a standard interior door?
The CLCTK and HIEMEY are listed for doors 1⅜ to 1¾ inches thick, with adjustable backsets of 2⅜ or 2¾ inches. The newliplace knob is intended for compatible mortise locks and has a spindle measurement to check. Measure your door and hardware before ordering.
Can I use the HIEMEY knob on a bathroom door?
It can operate a latch, but it does not lock. If you need privacy for a bathroom, the CLCTK is the option in this selection with a privacy lock.
Does the newliplace crystal knob include a mortise lock?
The product description presents it as a knob for replacing or updating an interior mortise-style door knob. It does not specify that a complete mortise lock is included, so check the listing and plan to use a compatible existing lock if needed.
What does the Allen key release do on the CLCTK?
The CLCTK description says the door can be unlocked from the outside with an Allen key in an emergency. This is an emergency release, not a keyed entry lock.
Final Recommendation
For a vintage-inspired brass knob with bedroom or bathroom privacy, the CLCTK is the most direct match because it includes a thumb-button lock and adjustable latch. Choose the HIEMEY for a non-locking hall or closet door, or the newliplace crystal knob when you want a decorative replacement for a compatible mortise lock. The best fit depends on your door measurements and the function you need.
