My Snap-Trak has been in use for over 30 years in very prestigious applications. It is installed around the perimeter of a wall or ceiling section and fabric or marine vinyl is then stretched tautly and evenly. Track releases when it's time to change or repair. Visit www.soundnice.net to see how it is used conventionally in building interiors. But it has been used many times in the marine industry. Sells for $1.30/ft.
