Aluminum Alloy Trim Tabs

The Lectrotab aluminum alloy trim tabs are uniquely designed to meet the needs of aluminum hulled boats and are an economical option for all boats. All aluminum alloy tabs are fabricated with an extremely strong "no-break" polypropylene hinge. The tabs are made of marine grade 6005-T5 aluminum alloy material that is equivalent in strength to 10 gauge stainless steel. All aluminum tabs are sealed with a corrosion resistant epoxy coating. Standard tabs are available in 9" (23cm) and 12" (30cm) chord lengths (chord is the length from the transom to the tab trailing edge) and in widths between 9" (23cm) and 48" (122cm). See specification chart for dimensional details. Custom designed tabs are also available with drop fins or supports.

Lectrotab specializes in providing customized tab designs. Please contact Lectrotab for your specific tab needs.
