Who It's For

These knobs are best for homeowners, landlords and DIYers who want an attractive polished brass privacy lock for bedrooms and bathrooms that installs without specialized tools and matches modern interiors. The set of five is useful for multi-room projects, rental units or larger homes where consistent hardware is desired.

Not ideal for exterior doors or situations requiring keyed entry or high security; if keyed access or heavy commercial duty is required, choose a keyed deadbolt or a higher grade commercial lock instead.
