Product Overview

This 10-foot fiberglass crossarm measures 5 inches by 5 inches and is built to mount on fiberglass or wood poles with diameters from 5 to 9 inches. The crossarm weighs 45 pounds and ships with all connection hardware included: one crossarm bracket, two 12-inch by 3/4-inch threaded rods for pole attachment, two 6-3/8-inch by 3/4-inch bolts for securing the crossarm to the bracket, and two end caps.

Available finish colors are bronze, black, white, gray, and custom options. The fiberglass construction is non-conductive and coated with UV-protective paint rated for 25 years. This crossarm carries a 7-year warranty.

Where This Product Fits Best

This crossarm is sized for poles in the 5 to 9-inch diameter range, with a maximum pole circumference of 28.25 inches. It pairs with both fiberglass and wood poles in that size class. The 10-foot length provides reach for mounting fixtures, banners, or signage where horizontal extension from the pole is required.

The fiberglass material suits installations where corrosion resistance matters, including coastal areas, industrial yards, and locations with chemical exposure. Because fiberglass is non-conductive, this crossarm is appropriate for applications near electrical infrastructure where conductive materials would present a concern.

Performance and Functional Considerations

Fiberglass does not rot, rust, or corrode. The material is stronger than equivalent steel in both compression and tension, which contributes to durability in high-wind conditions. The crossarm is designed to flex under load and return to its original shape rather than fracture.

The material does not sustain a flame because it contains no fuel source for fire. At 45 pounds, the crossarm is lighter than comparable steel or wood crossarms, which affects handling during installation.

Installation and Long-Term Use

The included bracket attaches to the pole using the two 12-inch threaded rods. The crossarm then bolts to the bracket with the two 6-3/8-inch bolts. End caps are included for finishing the crossarm ends. All connection hardware is galvanized.

Once installed, the UV-protective coating reduces weathering and color degradation over time. The fiberglass material does not require the retreatment or replacement cycles associated with wood crossarms in corrosive or high-moisture environments.

How This Fixture Is Commonly Used

Facilities use this crossarm to extend mounting points horizontally from a pole, typically for luminaires, cameras, signage, or banners. The 10-foot length provides substantial horizontal reach from the pole centerline, which affects fixture spacing and placement options in parking areas, roadways, and site perimeters.

The color options allow the crossarm to match existing pole finishes or site aesthetics. Custom color requests are available for projects with specific finish requirements. The non-conductive property is relevant for installations where electrical clearance or isolation is a factor in the site design.

Safety, Certifications, and Warranty

This crossarm is covered by a 7-year warranty. The fiberglass construction is non-conductive and does not sustain flame. The UV-protective paint is rated for 25 years.
