Best for traditional interiors that favor a dark, sophisticated finish. This mortise style set supports privacy locking on interior doors and is operable from both inside and outside with a key. Door thickness compatibility ranges from 1-3/8″ to 1-3/4″ (35–45 mm), making it a fit for many common interior doors. The set’s vintage look complements classic décor and can elevate bedrooms or baths. A caution: verify room-use needs, as privacy locking may not be ideal where code requires emergency egress in bedrooms or bathrooms.
Newliplace Antique Brass Door Knob Set
Best for updating older mortise hardware with a warm brass tone. The set replaces interior door knobs on doors 1-3/8″ to 1-3/4″ thick and is built from zinc alloy with a classic antique brass finish. It is a solid choice for rooms that benefit from vintage charm and durable construction. Limitations include compatibility with certain mortise mechanisms; always compare with your current lock system before purchasing.

It includes a dual-action skeleton key and a 5-pin cylinder for security and convenience. It fits doors 1-3/8″ to 1-3/4″ thick and is suitable for bedrooms or entryways where a vintage look is desired.

These glass knobs come with a spindle that fits mortise locks; the metal sleeve can adapt the spindle to 8 mm for broader compatibility. The set is ideal for interior doors such as bedrooms or decorative entryways where a high-end look is desired. A caution: glass knobs can be more prone to fingerprints and require careful handling during installation to avoid damage.

Buying Guide
What thickness should I expect? Most mortise sets herein fit 1-3/8″ to 1-3/4″ interior doors; measure your doors to ensure compatibility before purchasing.
