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 classic design of Tylo is at home in any décor. Its style lends a graceful finish to any door. This combo pack provides two locking points -- keyed entry and a keyed deadbolt. The complementary Antique Brass finish offers a warm feel with deep accents in the contours of the product. Bacteria can double every 20 minutes on an unprotected surface. Microban silver glass technology is incorporated during the manufacturing process and permanently binds the silver ions to the coating. Treated hardware continuously inhibits the growth of bacteria on the surface creating a cleaner product. Homeowners that install Kwikset hardware with Microban antimicrobial product protection are proactively protecting a frequently touched door surface, which helps to reduce the growth of microbes on the surface of the hardware.
