QUESTIONS & ANSWERS

Ask a Question

  • Will these attach to fiberglass tanks?

    If the fiberglass tank has a flat mounting point, and its dimensions match this adapter ring's dimensions, then yes it should work. Check the drawing on the product listing for the precise dimensions. You will probably want a more permanent way of securing it, such as stainless-steel bolts or such.
