Bennett Trim Tab 12" x 9" Sport Tab System [ST9]Bennett Trim Tabs are designed and manufactured with pride at the Bennett Marine plant in Deerfield Beach, Florida. Every Bennett system carries with it an accumulation of nearly 40 years of research, development, and testing and is designed to provide years of dependable service. Every trim tab is sheared and bent, not welded. Welding alters the properties of stainless steel which invites corrosion. Bennett actuators feature through hull hydraulics.
