Threaded on Both Ends

Unthreaded

Connect an electrical system to a ground. They are tapered at one end for easy driving.

Threaded on Both Ends—Threaded rods provide the best connection when joining two rods with a connector.

Copper-Plated Steel—These copper-plated steel rods provide high levels of conductivity and good corrosion resistance.

UL 467—All meet UL 467 for direct burial.

Grounding Rod Clamps


	Single-Nut Clamp, Floating Pressure Bar	Single-Nut Clamp, Two-Piece Design

Dual-Nut Clamp Lay-In Wire Two-Piece Design

Connect bare-copper ground wire to grounding rods.

Dual-Nut Clamp—Dual nut clamps give you more flexibility than single nut clamps.

U-Bolt Clamp—U-bolt clamps are the most adjustable and work with rods ranging in size from 3/8" to 1".

Floating Pressure Bar—Clamps with a floating pressure bar distribute pressure evenly over a large area, which creates more contact area for grounding.

Lay-In Wire—For clamps with lay-in wire, there’s no need to thread wire through them. Simply lay the wire into the clamp’s opening and fasten.

Two-Piece Design—Two-piece design clamps are easier to install onto bends and continuous loops than other single- and dual-nut clamps.

UL 467—UL 467 clamps meet a standard for direct burial.

Grounding Clamps for Welding

Designed specifically for use with welding circuits.

C-Clamp


Heavy Duty	No Twist	No Twist ABS Plastic Handle

C-clamps tighten with a handle. Use these multipurpose tools for strong clamping in nearly any application.

Heavy Duty—Heavy duty clamps have a strong frame that won’t spread when holding big workpieces, such as large diameter pipe and thick plate.

No Twist—No-twist clamps have jaws that move in unison to apply even pressure and prevent twisting while securing your workpiece. They’re also known as cantilever clamps.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

ABS Plastic Handle—Clamps with an ABS plastic handle have a cushioned grip that’s comfortable to hold.

Copper-Plated Steel Screw—Clamps that have copper-plated components prevent weld spatter from sticking.

Plier Clamp


Nonconductive

Plier clamps are good for light duty applications that require mobility, such as building a fence.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

Nonconductive—Nonconductive clamps won’t transmit electricity, meaning you can touch them while the power is on without disrupting the circuit.

Cable Support—Cable supports prevent cable strand breakage.

Spring Clamp


Standard	Flat Jaw

Spring clamps have an extended jaw that eases clamping. Both jaws carry current.

Flat Jaw—Flat-jaw clamps grip flat surfaces especially well. They have a larger contact area with the workpiece than standard spring clamps, so electricity flows more easily, but their jaw openings aren’t as large.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

Cable Support—Cable supports prevent cable strand breakage.

Magnetic Clamp


Magnetic Clamp	Magnetic Clamp with On/Off Switch	Multiple-Angle Magnetic Clamp with On/Off Switch

Magnetic clamps stick to metal surfaces on your workpiece, even oddly-shaped and sized ones. Compared to traditional clamps, they require less manual effort and are less limited by the amount of space available on your workpiece. However, you can’t use them on aluminum or nonferrous material, and their hold is usually less powerful than traditional clamps.

Multiple Angle—Multiple-angle clamps let you hold more than one workpiece at a time, at different angles.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

On/Off Switch—Clamps with an on/off switch let you engage and disengage the magnet for easy placement and removal of your workpiece.
