Electrical Wires & Cables

The spade terminal permits a fast wire connection, since the spade can be easily slipped over a stud without completely removing the fastener. Uninsulated terminals are the most cost-effective type of terminal and are ideal for use when specialized features are not required.

A section of PVC schedule 40 conduit which as been heated and bent to effect a 90 degree change in direction in a conduit run. A standard conduit bell is formed on one end while the other end is a spigot (plain) end. Both ends are solvent weld. Can be used above ground or buried and are suitable for concrete encasement.

The locking spade terminal has similar features to the spade, but with an interior notch that locks into place around the stud. Extra force is needed to remove from the stud, deterring accidental removal if the mount screw loosens. Uninsulated terminals are the most cost-effective type of terminal and are ideal for use when specialized features are not required.

Electrical conduit locknut holds conduit or fitting to PVC box.

The flanged spade terminal has similar features to the spade, but with turned up ends that stay secure even if the mount screw loosens. Insulated terminals are used when an insulated barrel is required and feature color-coding that signifies the correct wire gauge size.

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. Uninsulated terminals are the most cost-effective type of terminal and are ideal for use when specialized features are not required.

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.

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 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.

A section of PVC schedule 40 conduit which as been heated and bent to effect a 45 degree change in direction in a conduit run. Both ends of the bend are spigot (plain) end. Both ends are solvent weld. Can be used above ground or buried and are suitable for concrete encasement.

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

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 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.

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 …
