Test Leads and Cords

High-Current Test Clips

Test equipment that draws more than 10 amps of current. These clips are spring loaded to hold tight for hands-free testing.

Pipe Clips

Also known as a geophone clip, this clip has rounded jaws that clamp onto battery terminal lugs and other curved surfaces for hands-free testing.

Alligator Clips

Spring-loaded clips create a secure temporary electrical connection for hands-free testing.

Patch Cords

Hook up electrical testing equipment and create test circuits.

Material Handling

Routing Clamps

For use with a single line, these clamps brace pipe, tubing, and conduit directly against the mounting surface.

Strut-Mount Metal Routing Clamps

Route pipe, tubing, and conduit across strut channel.

Narrow-Space Strut-Mount Metal Routing Clamps

Even when these clamps are installed side by side, the clamping screws remain accessible. Use them to route pipe, tubing, and conduit across strut channel.

Strut-Mount Metal Routing Clamps for Insulated Pipe

Secure insulated pipe to strut channel without pinching the insulation or exposing the pipe. These clamps are sized for use with insulated pipe and have a plastic insert that creates a seal around the insulation to prevent the pipe from sweating, which can cause mold and corrosion.

Standoff Strut-Mount Metal Routing Clamps

Hold pipe, tubing, and conduit away from strut channel.

Connectable Plastic Routing Clamps

Join these clamps together to line up multiple pipes, cables, or tubes side-by-side, even when they are different sizes.

Threaded-Rod-Mount Clamping Hangers

Also known as conduit hangers, these hangers load from the bottom so you can add or remove material without removing the mounted hanger.

Adjustable Plastic Clamping Hangers

These hangers fit a range of material sizes. Push them closed to lock at the size you need. They provide a more secure hold on material than loop hangers.

Easy-Position Beam Clamps
for Pipe, Tube, and Conduit

Suspend material at any angle from the beam. Clamps have a fixed jaw that secures to the beam and a hanger that swivels 360° to position material and accommodate for misalignment.

Beam Clamps for Pipe, Tube, and Conduit

These clamps have a fixed hanger for rigid connections.

Stud-Mount Routing Supports

Attach these supports onto metal stud knockouts to route cable, conduit, and tubing through metal studs.

Clamps for Jumper Cables

Replace worn and broken clamps on jumper cables.

Light Duty Jumper Cables

These cables are for occasional use on cars and other small transport vehicles.

Jumper Cables

Thicker wires allow for a fast start on large trucks and industrial vehicles.

Electric-Powered Grippers

Unlike air-powered grippers, which leak air, these electric grippers won’t release dirt or particulates, making them good for pick-and-place assembly, packaging, and finishing jobs in labs, electronics plants, and other clean environments. Often used with mobile robots, all have a servomotor that opens and closes the grippers with equal force.

Robot-Ready Electric Grippers

Including a robot tool mount and electrical connectors, these grippers come ready to attach to robot arms with standard ISO 50 mounting hole patterns. Good for areas without compressed air, they use electricity to pick and place items in packaging, assembly, and machine-tending applications.

Electric-Powered Grippers without Motor

For applications without access to compressed air, such as mobile robots, these grippers use electricity to perform highly accurate pick and place tasks including assembly, finishing, and packaging.

Wire Terminals and Terminal Blocks

Screw-On Multi-Wire-Size Battery Terminal Clamps

Connect these clamps to a wide range of wire sizes.

Marine Battery Terminal Clamps

Made of lead, these clamps resist corrosion to stand up to marine environments. Use a lug to attach your cable to the stud.

Screw-On Battery Terminal Clamps

Insert your stripped cable into the compression nut and tighten; no crimping or heat is required.

Battery Terminal Clamps

Connect these clamps to cable with a crimping tool or by soldering.

Solder-Loaded Battery Terminal Clamps

When heat is applied, the flux and solder mixture creates a metallic bond that is nearly twice as strong as crimping or compression connections.

Heavy Duty Battery Terminal Lugs

Thicker walls than standard battery terminal lugs make these more durable.

Battery Terminal Lugs

Connect these lugs to cable with a crimping tool or by soldering.

Extra-Grip Battery Terminal Lugs

Serrations on both sides lock these lugs in place.

Screw-On Battery Terminal Lugs

Insert your stripped cable into the compression nut and tighten; no crimping or heat is required.

Solder-Loaded Battery Terminal Lugs

When heat is applied, the flux and solder mixture creates a metallic bond that is nearly twice as strong as crimping or compression connections.

Set Screw Lugs

The straight tongue improves conductivity by increasing the surface contact between the lug and your equipment.

Set Screw Lugs with Offset

An offset tongue gives you extra space to insert wire.

Screw-Down Split-Bolt Splices

Splice large size wires without special tools—insert your wires and tighten the hex nut to make a connection.

Electrical Connector Holding Tools

Safely hold electrical connectors in place when joining wires.

Bonding and Grounding

Grounding Plate Clamps

Eliminate the need to drive a new ground rod—these clamps connect grounding wire to an existing flat grounding surface, such as the lid of an electric meter box.

Grounding Rod Clamps

Connect bare-copper ground wire to grounding rods.

Grounding Pipe Clamps

Attach grounding wire to pipes.

Grounding Splices

Join two grounding wires to extend the length of your grounding connection or connect to an existing ground wire.

Grounding Straps

Straps fit around pipes and grounding rods.

Grounding Screws

Connect grounding wires to steel structures, fence posts, and transformers.

Grounding Lugs for Enclosures

Create a common grounding path for not only internal components and circuits, but also your enclosure’s body.

Lightning Protection

Protect electrical systems from lightning strikes on structures up to seventy-five feet tall.

Fuse Clamps

Secure a fuse into a fuse block to eliminate poor connections that can cause excessive heat and blown fuses.

Clip-On Heat Sinks

Clip these heat sinks onto circuit boards, semiconductors, and other heat-sensitive electrical components.

Pole-Mounting Kits for Enclosures

These kits come with everything you need to mount enclosures to round poles or beams. They clamp on to a range of pole diameters to hold enclosures securely in place.

Battery Terminal Adapters

Convert one battery terminal style to another.

Strut Channel Framing and Fittings

Strut Channel Brackets for Quick-Connect Clamps

These brackets have narrow slots compatible with quick-connect clamps for securing pipe and conduit on the channel side of struts without screws or tools.

Strut Channel for Quick-Connect Clamps

For compatibility with quick-connect clamps to secure pipe and conduit without screws and tools, this strut channel has narrow slotted holes.
