This Side Weatherbreaker by SunSetter is the perfect option for protection when sitting on your deck or porch. This weatherbreaker extends down 5 ft. to block out up to 660 percent of sun and wind-while letting the light and air in! These weatherbreakers easily attach to your deck or railing and can be removed in seconds. They also block drizzle and light elements-preventing napkins and papers from being blown off the table. This unit is compatible with motorized SunSetter units only.
