10 Foot Fiberglass Crossarm | 5 in x 5 in x 10 ft | Hardware Included | Fits 5 to 9 in Diameter Poles
This 10-foot fiberglass crossarm is a strong choice for outdoor lighting and utility applications where non-conductive, corrosion-resistant, and fire-resistant support is essential. Its high-strength FRP construction, 25-year UV protective coating, and galvanized hardware ensure long-term durability in demanding environments, while its ability to flex under wind load and return to shape reduces the risk of permanent damage. The lightweight design and included mounting hardware simplify installation on fiberglass or wood poles up to 9 inches in diameter. This crossarm is ideal for commercial and industrial sites exposed to weather or elevated fire risk.

Durable Construction
- Lightweight, easier to unload and install, saving on labor costs
- Does not rot, rust, or corrode.
- Non-conductive
- Does not break down with age, coated in 25-year UV protective paint
- Stronger than equivalent steel in compression and tension, providing excellent durability and longevity in high wind conditions
- Designed to bend, not break, meaning that poles can naturally bend due to weather conditions and will return to their original form
- Fire resistance: poles do not sustain a flame, as there is no fuel source for fire

Product Overview
This is a 10 foot fiberglass crossarm designed for use with fiberglass or wood poles up to 9 inches in diameter. The crossarm measures 5 inches wide and 5 inches high, with a total weight of 45 lbs. It is available in bronze, black, white, gray, or custom colors.
The crossarm is constructed from high-strength FRP and includes galvanized connection hardware and end caps. Brackets and all necessary mounting hardware are included for attachment to the pole and bracket.
The fiberglass material is non-conductive and does not rot, rust, or corrode. The crossarm is coated in 25-year UV protective paint for long-term durability.
This product is designed to bend under wind or weather load and return to its original form, providing resilience in demanding outdoor environments.
Where This Product Fits Best
This crossarm is suitable for commercial and industrial sites where non-conductive, corrosion-resistant support is required. It is commonly used in outdoor lighting, utility, and infrastructure applications where exposure to weather and environmental stress is expected.
The fiberglass construction is appropriate for areas where steel or wood crossarms may be subject to corrosion, rot, or electrical conductivity concerns. The fire-resistant properties make it suitable for locations with elevated fire risk.
It can be installed on both fiberglass and wood poles with diameters up to 9 inches. The available color options allow for visual integration with existing site aesthetics or compliance with local requirements.
Performance and Functional Considerations
The crossarm is designed to provide strength in both compression and tension, outperforming equivalent steel in these aspects. It is engineered to flex under load and return to its original shape, reducing the risk of permanent deformation or breakage in high wind conditions.
The non-conductive fiberglass material eliminates electrical conductivity concerns, supporting use in environments where electrical isolation is required. The crossarm does not sustain a flame and will not act as a fuel source in the event of fire exposure.
The 25-year UV protective coating maintains structural integrity and appearance over extended outdoor service. The included galvanized hardware resists corrosion and supports secure attachment to the pole and bracket.
Installation and Long-Term Use
The crossarm is lightweight at 45 lbs, making it easier to handle, unload, and install compared to steel alternatives. All required mounting hardware is included, with brackets and threaded rods sized for secure attachment to poles up to 9 inches in diameter.
End caps are provided to protect the crossarm ends from moisture and debris. The fiberglass construction does not break down with age, and the UV coating supports long-term outdoor use without significant maintenance.
The crossarm is designed to accommodate natural pole movement and flexing due to wind or weather, returning to its original form without permanent damage. The fire-resistant properties further support long-term reliability in exposed environments.
How This Fixture Is Commonly Used
Once installed, the crossarm provides a stable, non-conductive mounting point for lighting fixtures or other equipment. The included hardware allows for direct attachment to the pole and bracket, with end caps protecting the crossarm from environmental exposure.
The fiberglass material does not require ongoing maintenance for corrosion or rot, and the UV coating maintains the crossarm's appearance and structural integrity over time. You can expect the crossarm to flex under wind load and return to its original shape, reducing the risk of damage during storms or high winds.
The fire-resistant and non-conductive properties support use in areas with electrical equipment or elevated fire risk, without the need for additional protective measures. The color options allow you to match the crossarm to site requirements or preferences.
Safety, Certifications, and Warranty
The crossarm is non-conductive and fire-resistant. The fiberglass construction does not rot, rust, or corrode, supporting safe long-term use in outdoor environments.
All connection hardware is galvanized for corrosion resistance. End caps are included to protect against moisture ingress.
LED Lighting Supply provides a 7 year warranty on this crossarm.
