Electrical Wires & Cables

The Sigma ProConnex Conduit Nipples are used in conjunction with locknuts to provide a short raceway between two outlet boxes or metal enclosures.

Disconnect terminals securely attach the female disconnect over the male tab, while allowing for quick and easy detachment if two wires need disconnected in the future. Uninsulated terminals are the most cost-effective type of terminal and are ideal for use when specialized features are not required.

The Sigma ProConnex EMT Set Screw Connectors are used to secure and terminate steel EMT conduit to an outlet box or enclosure. These die-cast connectors are suitable for indoor applications and approved for concrete-tight applications when taped.

The ring tongue is a traditional style terminal with the safest and most fail-safe connection since it cannot be removed without first taking off the mounting screw. Insulated terminals are used when an insulated barrel is required and feature color-coding that signifies the correct wire gauge size.

Elbow use with schedule 40 non-metallic solvent weld fittings. Non-metallic, non-conductive, will not rust or corrode. Fittings sold separately. Straight end to belled end.

Electrical conduit locknut holds conduit or fitting to PVC box.

WireGard twist-on wire connectors are designed for general purpose applications requiring the connection of 2 or more copper wires. WireGard connectors feature a straight type Polypropylene shell with side knurling for an easy grip. The inner spring is zinc-plated to resist corrosion and has a tight square profile to make quick secure contact with wires and ensure connections with positive continuity. These all purpose connectors require fewer turns to meet required torque and meet or exceed UL pull out and dielectric test requirements. The tough thermoplastic shell shields against environmental extremes and resists chemical action from hydrocarbons, diluted acid or alkaline solutions. The high …

Sigma's weatherproof closure plugs help keep moisture from the electrical wiring by closing unused holes in weatherproof boxes, extension rings or covers.

Sigma's weatherproof one-gang blank covers are used to protect junction boxes or boxes not in use. Stamped steel blank covers are powder coated for maximum corrosion resistance and compliment one-gang weatherproof boxes installed in wet, damp or dry locations. Cover includes hardware and gasket.

The Sigma ProConnex Conduit Locknuts are used for securing Rigid conduit, IMC and other threaded connectors to a steel outlet box or metal enclosure. These zinc-plated steel locknuts are recommended for indoor applications.

The Sigma ProConnex Rain-Tight EMT Compression Couplings are used to connect two lengths of steel EMT conduit. These die-cast zinc couplings are approved for concrete-tight and rain-tight applications.

The Sigma ProConnex Rain-Tight EMT Compression Connectors are used to secure and terminate steel EMT conduit to an outlet box or enclosure in a dry or damp location. They are recommended for indoor and outdoor applications and approved for concrete-tight applications.

Bullet terminals securely attach the female receptacle over the male bullet, while allowing for quick and easy detachment if two wires need disconnected in the future. Often used in automotive applications. Insulated from the barrel to the receptacle end, fully insulated terminals are used when an insulated barrel is required and feature color-coding that signifies the correct wire gauge size.

Rubber grommets cover and cushion hole openings, protecting the cables and wires that pass through from abrasion or damage from sharp corners or edges.

The ring tongue is a traditional style terminal with the safest and most fail-safe connection since it cannot be removed without first taking off the mounting screw. Insulated terminals are used when an insulated barrel is required and feature color-coding that signifies the correct wire gauge size.

The parallel splice connector allows for quick, easy wire insertion to splice wire during a continuous run. Wires insert from both ends and overlap, with a single crimp in the center. Resistant to melting and corrosion, high temperature terminals are ideal for high heat applications such as ovens, motors and light fixtures.

The closed end connector is for splicing two or more wires that meet at a junction. Connection secured by crimping. Insulated terminals are used when an insulated barrel is required and feature color-coding that signifies the correct wire gauge size.

Sigma's weatherproof one-gang blank covers are used to protect junction boxes or boxes not in use. Stamped steel blank covers are powder coated for maximum corrosion resistance and compliment one-gang weatherproof boxes installed in wet, damp or dry locations. Cover includes hardware and gasket.

Rubber grommets cover and cushion hole openings, protecting the cables and wires that pass through from abrasion or damage from sharp corners or edges.

The butt splice connector allows for quick, easy wire insertion to splice wire during a continuous run. Wires insert from both ends and meet in the middle at the built-in wire stop. The connector must be crimped at both ends. Uninsulated terminals are the most cost-effective type of terminal and are ideal for use when specialized features are not required.

The Sigma ProConnex Squeeze Connectors are used to terminate AC, MC or FMC/RWFMC to a knockout in a dry location box or enclosure. These die-cast zinc connectors are equipped with a tri-combo screw and are suitable for aluminum or steel cable and conduit.

Bullet terminals securely attach the female receptacle over the male bullet, while allowing for quick and easy detachment if two wires need disconnected in the future. Often used in automotive applications. Uninsulated terminals are the most cost-effective type of terminal and are ideal for use when specialized features are not required.
