Overview
Fitting a bedroom or bathroom door, this Probrico knob set screws on to the door and includes the latch and strike plate. The round ball shape and matte black finish give a modern colonial look.
The reason to buy is enough matching knobs for several rooms, with the latch parts included in the set. The limit is lock detail: the listing mixes keyless and push button wording, so check how the privacy lock works.
Who it's for
Bedrooms, bathrooms and offices needing a privacy knob are the setting, in both residential and commercial spaces. Skip it for a front entrance, since the listing says indoor use.
Pros and cons
- Six knobs in one pack
- Latch and strike plate included
- Universal hand fit
- Stainless steel construction
- Door thickness range not listed
- Lock type wording is unclear
- Indoor use only
Performance notes
A screw on attachment holds the knob to the latch, so tight fit depends on the door bore and thickness matching. Stainless steel resists wear on frequently turned knobs. A matte finish hides fingerprints.
