As the industry leader, Kwikset has provided trusted security for over 60 years and has become synonymous with security, peace of mind, style and innovation. Our innovative round design fits a standard 2-1/8" drilled door, allowing easy installation with a standard screwdriver. This privacy knob/lever is best used in interior bed and bath applications where privacy is required. Both knobs/levers are locked or unlocked by turn button inside. The outside knob/lever can be unlocked by an emergency key. The Polished Brass finish adds to the traditional look and feel of the product and makes a classic statement.
