BDT 110.00 / set Scope based

A Class 1 solid aluminum air terminal base plate is a critical component for lightning protection systems installed on structures not exceeding 75 feet (23 meters) in height. These components are designed to meet UL 96 standards and provide a secure, conductive mounting point for aluminum air terminals (lightning rods).

Key Specifications for Class 1 Aluminum Bases

Material: High-quality conductive aluminum, often die-cast or stamped to resist corrosion while maintaining electrical continuity.
Rod Compatibility: Designed to accept 1/2-inch (12.7 mm) diameter solid aluminum air terminals, which is the minimum required diameter for Class 1 installations.
Conductor Connections: Typically features a bolt-pressure or crimp-style cable clamp to secure the main lightning conductor.
Threading: Most bases use a 5/8-inch internal thread or external stud to engage with standard adapter-type or threaded-end air terminals.

Common Types of Base Plates

Manufacturers like Harger, Thompson Lightning Protection, and East Coast Lightning Equipment offer various mounting configurations:

Flat Surface Bases: Used for horizontal or vertical mounting on flat roofs or walls.
Adhesive Bases: Designed for flat roofs where mechanical fasteners (screws) cannot be used, utilizing a specialized adhesive.
Saddle Bases: Designed to fit over the ridges of sloped roofs or "standing seams".
Offset/Swivel Bases: Allow the air terminal to be set perfectly perpendicular even on sloping surfaces.
