Universal Ground Clamps
Ordering Information
EM 5500
A 12" copper strip with a brass bolt assembly. Connects #6–#14 AWG, fits all grounding electrodes 3/8"–3 1/2" OD.
Application
Connecting ground wires to water pipes, ground rods, and power masts.
Features
- Fits around any size water pipe, ground rod, or power mast.
- Works with all the materials commonly used in grounding electrodes, i.e. copper water pipes, galvanized pipes, copper clad ground rods, plain steel ground rods.
- Connects all the ground wire sizes from #14 AWG to solid #6.
- Flat bottom on dome-shaped washer will not nick small gauge wire.
- Can be daisy-chained to be able to fit around very large diameter pipes.
- Ground wires can be added or changed without removing ground clamp.
- Tin-plated version available to be used with aluminum power masts.
- EM 5510 and EM 5517 versions (below) have two extra flat washers so that small gauge (#10, #12, #14 AWG) wires can be connected between washers while #6 solid bond wire is captured in through hole. Therefore, one ground clamp can be used where two were necessary before.
Standard packaging: 10/bg, 100/bx, 15 lb/bx. [Please note: There is no minimum
order. When ordering, the number you enter for “Quantity” will indicate
the number of clamps, not the number of bags or boxes.]
EM 5507
7" version connects #6–#14 AWG, fits all grounding electrodes 3⁄8"–2" OD.
Add suffix -T for tin-plated version.
Standard packaging: 10/bg, 100/bx, 13 lb/bx. [Please note: There is no minimum
order. When ordering, the number you enter for “Quantity” will indicate
the number of clamps, not the number of bags or boxes.]
EM 5510
12" version, connects #6–#14 AWG wires for grounding electrodes from 3/8" to 3 1/2" OD. Clamp has two extra flat washers to connect both station ground wires and bond wire simultaneously.
Add suffix -T for tin-plated version.
Standard packaging: 10/bg, 100/bx, 15 lb/bx. [Please note: There is no minimum
order. When ordering, the number you enter for “Quantity” will indicate

order. When ordering, the number you enter for “Quantity” will indicate
the number of clamps, not the number of bags or boxes.]
Offered also in lengths of 9, 12, or 14 inches, and with larger hole (all below).
Application
Connecting ground wires to water pipes, ground rods, and power masts. (See application photo under EM 5909.)
Features
- Fits around any size water pipe, ground rod, or power mast.
- Works with all the materials commonly used for grounding electrodes, i.e., copper water pipes, galvanized pipes, copper clad ground rods, plain steel ground rods.
- Connects all the ground wire sizes from #14–#6 AWG solid or stranded.
- Can be daisy-chained to be able to fit around very large diameter pipes.
- Ground wires can be added or changed without removing ground clamp.
- Tin-plated version available to be used with aluminum power masts.
- Clamp is installed and wire is attached from the same side, making application easier in confined spaces.
- Available with a slotted ground wire hole to accommodate two wires simultaneously (see picture below). Add suffix -S to part number.
- Available as “suitable for direct burial.”
