Extension Cord Adapters
Change the connection style between an outlet and your equipment.
NEMA TT-30 adapters are often used to power RVs.
Adapters with a 90° elbow plug sit flush against wall outlets to fit in tight spaces.
Adapters with a power-indicating light have a light on the socket that illuminates when the adapter has power.
Adapters with a handle make it easy to pull plugs out of sockets.
STW and SJTW adapters have a water-resistant outer insulation. STOW and SJTOW adapters have an oil- and water-resistant outer insulation.

Abrasion-Resistant Turn-Lock Extension Cords
Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough areas. The insulation also resists water. Give the connectors a quarter turn to lock in place; they remain secure in high-vibration applications.

Ground-Monitoring Turn-Lock Plugs and Sockets
Check the status of a ground connection—a green light signals that connectors have power and are safely grounded. A red light indicates power only. The lights are visible from any angle for quick identification. A quarter turn locks connectors in place to remain secure in high-vibration applications and prevent accidental disconnection.

Washdown Turn-Lock Connectors and Cords
When mated, connectors meet NEMA 6P for protection against corrosion and washdowns. All have a multiple-ring seal and rubber housing to keep out liquid. They resist heat, oil, and chemicals. A quarter turn locks them in place to remain secure in high-vibration applications and prevent accidental disconnection.
Plugs mate with female receptacles and female sockets with an attached cover.
