The Fiberglass Extension Arm, measuring 36 inches, is engineered for durability and strength in demanding aerial hardware applications. With an aluminum end fitting and a ductile iron base that is hot dip galvanized, it offers robust performance while resisting corrosion. This extension arm is specifically designed to accommodate 5/8" mounting hardware with a secure 5/8" x 2" stud, ensuring easy installation and stable operation. Enhanced with integrated cleats, it effectively prevents rotation when mounted on wood poles, adding to its reliability in various conditions. The fiberglass rod, coated with a gray ultraviolet protective veil, not only guarantees long-lasting use but also ensures that the arm can withstand exposure to harsh outdoor elements, making it suitable for a wide range of aerial line hardware applications.
