Crossarms (also known as bullhorns) are horizontal structures built to support light fixtures, power lines, and communication cable components. These engineered components ensure reliable service and safety across electrical networks.

What Are Utility Pole Crossarms?

LED Lighting Supply's utility pole crossarms are horizontal beams attached to utility poles. They are designed to support electrical conductors and create necessary clearance between power lines. Crossarm length is a critical component for ensuring proper spacing and support for the power lines. Whether supporting primary or secondary wires, quality crossarms demonstrate exceptional strength and durability while maintaining system integrity under various environmental conditions.

Types of LED Lighting Supply Crossarm Materials

Wood Crossarms

Wood crossarms remain the industry standard due to their proven performance and cost-effectiveness. Manufactured from pressure-treated southern yellow pine or similar wood, each wood crossarm is known for its durability. The longevity of wood crossarms is enhanced by the use of pressure-treated wood, which protects against rot, decay and insect damage. LED Lighting Supply's wood crossarms require minimal maintenance when properly installed.

Fiberglass Crossarms

Fiberglass crossarms are a favored choice due to their lightweight design and superior resistance to rot, rust, decay, and corrosion. Offering a service life of 80+ years, the structural integrity of fiberglass crossarms ensures they are an ideal solution for coast regions and locations with harsh environmental conditions.

Fiberglass crossarms can be customized to accommodate specific drop requirements, preventing potential electrical hazards and equipment damage.

Pole Cross Arm Benefits

Selecting the proper crossarm for your project provides several advantages.

• Enhanced Durability: Quality crossarms resist environmental damage. The need for durable crossarms is critical in maintaining the integrity of power infrastructure.
• Improved Safety: Properly engineered crossarms maintain critical line spacing
• Cost-Effective: Long-lasting materials minimize lifecycle costs. Crossarms often come in pairs to provide additional stability and support for heavy loads.
• Reliability: Strong crossarms reduce service interruptions
• Regulatory Compliance: Manufactured to meet industry standards

Selecting the Proper Crossarm Solution

When choosing between materials, consider environmental conditions, load requirements, service life expectations, and budget considerations.

Common Crossarm Configurations

Crossarms are available in various configurations:

• Standard Single Crossarm: Most common for typical line arrangements
• Double Crossarm: Provides additional strength for heavy loads
• Braced Crossarms: Include additional angles and braces for enhanced stability
• Custom Configurations: Engineered for unique applications

Each configuration comes in multiple lengths to accommodate different pole types and spacing requirements. Standard dimensions for wood crossarms include sizes like 3 ¼ inches x 4 ¼ inches, which are commonly used in utility poles.

Installation Best Practices

Proper installation of pole crossarms ensures optimal performance. Mounting hardware should be appropriately sized, braces must be correctly positioned, pre-drilled holes ensure proper alignment, and weatherproof hardware prevents premature corrosion.
