air terminal parts

Air Terminals (lightning rods) — Available in copper and aluminum, pointed or rounded.
Bonding
Bonding — Used to join metallic bodies such as roofs, gutters, water and gas pipes, satellite dishes, AC units, flues, structural steel, etc.
Cable Splicers
Cable Splicers — Available in copper or aluminum, depending on the type of cable being used. Used to branch off runs of cable.
Thru roof assemblies


Thru-roof/wall assemblies — Used when penetration of roof or wall are necessary.
conductor
Conductor — Available in copper or aluminum. We offer many different types of conductor depending on your particular application.
Cable Supports
Cable supports/fasteners — Available in copper or aluminum. We offer many different types of supports/fasteners depending on the application that works best for you.
Ground Rods

Ground Rods — Typically 10' long and available in numerous diameters, depending on your requirements and soil conditions. Minimum of two should be used on any structure.


Basic Parts Needed:

Protecting your home or business is a matter of contacting a professional, qualified to design and install a certified lightning protection system that is uniquely special for your building. A protection system is typically made up of the following components:
  • LIGHTNING PROTECTION - AIR TERMINALS: Also referred to as lightning rods. These copper and metal rods are vertically mounted on the roof at various high points on a house. Air terminals are positioned to project above the roof line, the rods are designed to intercept the lightning strike.

  • LIGHTNING PROTECTION MAIN CONDUCTORS: These cables are made of copper or aluminum and connect air terminals to the grounds.

  • LIGHTNING PROTECTION GROUNDS: Main conductors are set at least 10 feet deep in the earth and are attached to metal grounding rods. Special grounding requirements are sometimes necessary in sandy or rocky soil. The energy is directed into the ground as current flows through the rods. Then the chance for injury or damage is effectively eliminated.

  • LIGHTNING PROTECTION BONDS: The bonding connects grounded metal objects to the main conductor cable and prevents sideflashes, (lightning jumping between two objects.)

  • LIGHTNING ARRESTORS: Arrestors protect wiring and appliances from lightning induced power surges. A surge is an increase in electrical current due to a lightning strike on or near a power line. Kitchen appliances, computers, televisions and sump pumps are all vulnerable to unexpected surges.

  • LIGHTNING PROTECTION FOR TREES: It is recommended that any tree taller than your home or within 10 feet of it be equipped with a lightning protection system. Trees do not offer protection and many homeowners choose to have trees protected for their own value. An unprotected tree nearby can create a side flash of lightning to you house.
