About Wire and Cable

Low-Voltage Cable

Rated to 12 volts DC, this cable is often used in low-voltage applications such as battery and vehicle wiring and radios. Also known as GPT cable.

Direct-Burial Cable

Weather-resistant insulation makes this cable suitable for outdoor use and direct burial without conduit.

Duct-Rated Communication and Security System Cable

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use it in low-current circuits such as intercoms and security systems.

Riser-Rated Communication and Security System Cable

This cable is approved for use in vertical shafts and large facilities with multiple levels. It's often used for low-current circuits such as intercoms and security systems.

Coiled Communication Cable

After extending to full length to provide added reach, this cable retracts and self-coils for tangle-free storage. It's often used with low-current circuits such as microphones and headsets.

Communication and Security System Cable

Connect low-current circuits such as intercoms and security systems to a building's electrical system in single-level facilities.

Thermostat Cable

Hook up thermostats, air-conditioning units, and other low-voltage equipment.

Riser-Rated Fire Alarm Cable

This cable is approved for use in vertical shafts and large facilities with mulitple levels for critical circuits such as fire alarms and smoke detectors.

Duct-Rated Fire Alarm Cable

Also known as plenum cable, this cable has low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. Use in critical circuits such as fire alarms and smoke detectors.

Audio Cable

Hook up speakers, intercoms, and other low-current devices to a building's communication wiring.

Vehicle Wire

Also known as primary wire, this wire meets SAE standards for low-voltage wiring in trucks, boats, trailers, and other vehicles.

Vehicle Wire Assortments

Keep spools of vehicle wire in multiple colors on hand.

Battery Wire

Connect batteries in vehicles and generators.

Deutsch-Style Power Cords

Use these cords in vehicles and other agricultural and construction equipment.
