IMPORTANT ORDERING INSTRUCTIONS FOR GROUND ROD CLAMPS:

It is important to get clamps that are properly sized for your ground rods.  You MUST measure your ground rods accurately before ordering clamps!  The clamps are not one size fits all.  Do not rely on store shelf labels or product tags on your ground rods.  Measure them yourself.  The best way to do this is with inexpensive calipers.  Our ground rods clamps are made for ground rods of the following sizes:

    Trade size:        Actual measurement:   

    1/2”                   .500”      or     1/2”   

    5/8”                   .560”      or     9/16”

    3/4”                   .675”      or     11/16” (approx.)

Flat joining clamps will join two (or more) lengths of copper strap when the end of your strap doesn’t happen to end at a ground rod.  Hardware is stainless steel with nylock nuts.  

Attach four Alpha Delta surge units to your ground rod.  A perfect way to ground your vertical antenna and provide surge protection on outgoing coax lines at the same time.  Clamps can also be used as a quick and easy “single point ground” before cables enter the building.   Clamps are made entirely from copper and include a copper ground lug to fit up to a #4 wire, and secure with stainless steel hardware and nylock nuts.  Designed for 5/8” ground rod (see ordering instructions above).  Click pic for larger version.

These clamps are a simple and effective way of attaching ground rods to your flat copper strap.  Copper strap passes right through the center of the clamps and does not require drilling holes through strap.  They also provide a convenient place to join two lengths of strap.   Hardware is stainless steel with nylock nuts.   See Anti Oxidant Connection Grease below for assembly instructions.
