Key Features

• Durable construction: Made from stainless steel with a matte black finish to resist everyday wear while improving the look of interior doors.
• Easy installation: Installation requires only a screwdriver and uses an alignment post so a single person can fit the knob quickly without advanced skills.
• Fits standard doors: The latch adjusts for 2-3/8in or 2-3/4in backset and the reversible knob works for left or right handing on 1-3/8in to 1-3/4in door thickness.
• Wide application: Intended for bedrooms, bathrooms and home offices where a keyless locking function is appropriate.

Who It's For

These knobs suit homeowners, landlords and renovators who want an affordable, modern-looking privacy knob for interior rooms. They are a good choice when multiple doors need the same finish and simple keyed security is not required, such as rental bedrooms and guest baths.
