As the industry leader, Kwikset has provided trusted security for over 70 years and has become synonymous with security, peace of mind, style and innovation. The attractive, traditional colonial design of the Cove makes a simple yet elegant statement in any home. Both levers/knobs can be operated by a key on the outside or thumb turn on the inside. The crisp, clean appearance of the Satin Nickel finish adds to the overall look of the product and brings a modern feel.
