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. Kwikset Mobile Home locks are made especially to fit mobile home doors. This passage knob/lever is best used on interior hall and closet applications where no locking is required. The knob/lever is reversible and mounts on both left and right handed doors. The Polished Brass finish adds to the traditional look and feel of the product and makes a classic statement. 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.
