- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: Neoprene Rubber Gaskets: -20° to 190° F
Silicone Rubber Gaskets: -100° to 500° F - Tubing: Use with steel
Bolt clamps have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully-grounded system. They have fair corrosion resistance.

Grounding Rod Clamps
Connect bare-copper ground wire to grounding rods.
Dual nut clamps give you more flexibility than single nut clamps.
U-bolt clamps are the most adjustable and work with rods ranging in size from 3/8" to 1".
Clamps with a floating pressure bar distribute pressure evenly over a large area, which creates more contact area for grounding.
Two-piece design clamps are easier to install onto bends and continuous loops than other single- and dual-nut clamps.
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.
UL 467 clamps meet a standard for direct burial.

Grounding Clamps for Welding
Designed specifically for use with welding circuits. Clamps that are copper or have copper-plated components prevent weld spatter from sticking.
C-clamps tighten with a handle. Use these multipurpose tools for strong clamping in nearly any application. 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 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. Clamps with an ABS plastic handle have a cushioned grip that’s comfortable to hold.
Plier clamps are good for light duty applications that require mobility, such as building a fence. Nonconductive clamps won’t transmit electricity, meaning you can touch them while the power is on without disrupting the circuit.
Spring clamps have an extended jaw that eases clamping. Both jaws carry current. 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.
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. Clamps with an on/off switch let you engage and disengage the magnet for easy placement and removal of your workpiece. Multiple-angle clamps let you hold more than one workpiece at a time, at different angles.
Cable supports prevent cable strand breakage.

Lightning Protection
Protect electrical systems from lightning strikes on structures up to seventy-five feet tall. When replacing or adding components to an existing system, choose components that match your existing material. For a new system, choose components of the same material.
Rod bases can be mounted horizontally or vertically.
Wire clamps fold around the wire.
Bonding plates electrically bond your system to a metallic object.
Parallel connectors accept lightning wire and rods.
Joint compounds are recommended for use in corrosive environments. Apply at connection points.
