This 6 foot fiberglass crossarm is a strong choice for supporting lighting or utility equipment on fiberglass or wood poles up to 9 inches in diameter, especially in environments where corrosion, electrical conductivity, or maintenance are concerns. Its high-strength FRP construction resists rot, rust, and corrosion, while the non-conductive and fire-resistant properties enhance safety in utility and lighting applications. The crossarm's ability to flex and return to shape under wind load is valuable for outdoor installations in commercial, industrial, or sports facilities.
