Insulates through the entire cross-section
The all composite cross bar from Polygon utilizes an engineered composite structure that results in excellent retention of mechanical and physical properties at elevated temperatures. This all-composite cross bar eliminates the need for traditional metallic cross bars that need secondary insulation that is augmented with an additional layer of insulative paint.
