Step up to designer styles and superior security with Kwikset Signature Series products. Tustins fashionable wave silhouette design is the perfect complement to homes with inspired style. This half-dummy, or trim function, is surface mounted on doors where only a pull is required. The crisp, clean appearance of the Satin Nickel finish adds to the overall look of the product and brings a modern feel. 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.
