Industrial mounting frames are used with I.C.E. 300 Series Lightning Arrestors for attaching units directly to ground rod tops (keeping lead inductance to a near-zero minimum). This mounting method provides the highest possible performance
for voltage protection. And they're built as if we're expecting you to be hit time after time. Upper horizontal mounting plate is pre-threaded and 1/2" thick solid 6061-T654 I aluminum bar stock, tower section is prefitted at factory and
measures a bruising 1" X 1-1/2"- solid. Set screw that holds assembly to ground rod is stainless steel 1/4-20 Phillips head, balance of mounting hardware also 18-8 stainless steel.

Boring of lower section is designed to comfortably fit top of ground rod by simply sliding the whole assembly over the top of the rod after coating both surfaces with conductive copper-loaded anti-oxidant compound (provided). Bore, size is
approximately .015-.020 larger than rod to keep the fit tight, the frame horizontal, and prevent entry of moisture, dirt, insects, etc. Units are machined in one, two, and four-unit varieties indoor or outdoor use, accepts direct rain /
snow exposure. Each unit is packed with anti-oxidancompound, #8-32 screws for arrestor chassis mounting, weight approximately 2 pounds.
