HEX Lightning Air Terminals – Copper Aerial Rods, Multiple Point Spikes & Terminal Bases

HEX lightning air terminals are the conventional (Franklin-type) strike-termination parts of a building lightning-protection system: an electrolytic-copper aerial rod, with or without a multiple-point spike on top, fixed to the roof or wall on a terminal base that also takes the down conductor. HEX supplies the parts separately or as ready assemblies. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

At a glance

• Aerial rods: electrolytic copper, 15 mm dia, 5/8" thread, 500 / 1000 / 2000 mm, with lock nut
• Multiple point: copper / copper alloy, for 16 mm (5/8") and 20 mm (3/4") rods
• Terminal base: copper-plated brass (gunmetal on request), four fixing holes, M16 / 5/8" or M20 / 3/4" thread

Why choose HEX air terminals

• Electrolytic copper rods with a lock nut, in three lengths.
• Multiple point or single point — rods can be installed with or without the multiple-point spike.
• One base for rod and down conductor — the terminal base fixes the aerial rod and the down conductor together.
• Ready assemblies save sourcing three parts separately.
