CloZures® -  When curtains and shades just don't work

CloZures® are a simple and elegant solution for replacing those dusty curtains or broken shades. They will make your boat feel cleaner and larger. The shutters offer 100% UV protection and will make your boat’s interior 15 deg. cooler on a hot sunny day. As opposed to curtains, sunlight will filter through the shutters so the interior remains bright and cheery. When closed at night the shutters provide 100% privacy.
"After 10 years of use in a very harsh marine environment and installations on thousands of boats, the CloZures® have achieved a stellar reputation."
