This 8 foot fiberglass crossarm is a strong choice for outdoor lighting or electrical support on fiberglass or wood poles up to 9 inches in diameter, especially in environments exposed to weather, moisture, or corrosive elements. Its non-conductive, fire-resistant FRP construction ensures electrical safety and structural reliability, while the UV protective coating and galvanized hardware minimize maintenance and extend service life. The crossarm’s ability to flex under wind load without permanent deformation is valuable in storm-prone areas. It is well suited for commercial, industrial, and utility sites where durability, safety, and low maintenance are priorities.

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
  • Color selection: Bronze, Black White or Grey

Product Overview

This 8-foot fiberglass crossarm provides a horizontal mounting member for post top lighting and architectural site lighting installations. It fits fiberglass or wood poles up to 9 inches in diameter.

The crossarm measures 5 inches wide by 5 inches high and includes a mounting bracket, threaded rods, connection bolts, and end caps. It is available in bronze, black, white, gray, and custom colors.

Core Performance and Output

This crossarm is an 8-foot structural component, not a light-producing fixture. Its 5-inch by 5-inch fiberglass body provides a fixed horizontal support profile for pole-mounted lighting layouts.

The supplied data does not establish fixture weight limits, EPA ratings, wind ratings, or supported fixture quantities. Final pole loading must account for the complete crossarm, bracket, hardware, and mounted equipment arrangement.

Adjustability and Control Options

The crossarm uses a bracket connection with two 12-inch by 3/4-inch threaded rods for attachment to the pole. Two 6-3/8-inch by 3/4-inch bolts attach the crossarm to the bracket.

No lighting controls, electrical components, or adjustable arm positions are stated in the supplied product data. The crossarm position is established during installation.

Longevity and Reliability

The fiberglass construction does not rot, rust, or corrode. It is non-conductive and fire resistant.

The crossarm is coated with 25-year UV protective paint. The fiberglass structure is designed to bend under weather-related loading and return to its original form.

Build Quality and Physical Characteristics

The crossarm is constructed from high-strength FRP fiberglass and weighs 33 pounds. It measures 8 feet long, 5 inches wide, and 5 inches high.

Included hardware consists of one crossarm bracket, two threaded rods, two crossarm-to-bracket bolts, and two end caps. The maximum supported pole diameter is 9 inches, with a maximum pole circumference of 28.25 inches.

Where This Product Fits Best

This crossarm fits pole-mounted layouts where an 8-foot fiberglass support member is needed for decorative and architectural outdoor lighting arrangements. It is intended for attachment to fiberglass or wood poles within the stated diameter limit.

  • post top lighting
  • architectural site lighting
  • pedestrian area lighting
  • decorative outdoor lighting

Fiberglass construction suits installations requiring non-conductive, UV-resistant, fire-resistant, and corrosion-resistant material performance. Pole diameter, total loading, and hardware placement must match the completed installation.

Installation and Long-Term Use

The bracket mounts to the pole using the included threaded rods. The crossarm then attaches to the bracket with the included bolts, and end caps close the open ends.

Mounting height is determined by the pole and lighting layout, not by the supplied crossarm data. Installers must confirm pole diameter does not exceed 9 inches and verify the complete mounted load before installation.

How This Fixture Is Commonly Used

For post top lighting and architectural site lighting, the crossarm establishes an 8-foot horizontal mounting span at the pole location. The bracket-and-rod assembly secures the arm around the pole.

Layout patterns must account for the crossarm length, pole position, and final mounted equipment arrangement. A wider horizontal arrangement can affect pole loading and requires verification against the pole and fixture requirements.

Safety, Certifications, and Warranty

The fiberglass crossarm is non-conductive and fire resistant. Galvanized connection hardware and end caps are included.

This product includes a 7-year warranty. No certifications are stated in the supplied product data.
