About Extension Cords

Abrasion-Resistant Extension Cords
Thick insulation protects the internal wires of these cords, so they can be used in high-traffic areas and over rough surfaces. The industry designation is STW, so the insulation resists water.
Cords with a NEMA 14-50 plug and socket have a high current rating and are often used to power electric vehicles. The light on their socket illuminates when the cord has power. Their plug and socket have handles, making them easy to grip when plugging or unplugging them.
Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.

Extension Cords with Inline Outlet Boxes
Avoid the clutter of multiple extension cords and overcrowded outlet strips—these extension cords have outlet boxes spread evenly along their length. They’re great for powering temporary workstations and areas with few wall outlets, such as construction or maintenance sites.
Each outlet box has cord grips on both ends for a connection that isn’t easy to yank out. The cord grips also take strain off the cord if it’s bent or pulled. Insulated with rubber and SOOW designated, these cords resist breaking down from oil, water, and chemicals. They won’t tear if dragged along the ground, and their outlet boxes won’t crack if dropped.
Cords with six outlets have an outlet box at the end.
Cords with seven outlets can be attached to another cord, so you can extend the length of your run.

Power Cords
Connect equipment and devices to a power supply.
Cords with a NEMA 14-30 or 14-50 plug are often used to power electric vehicles. They have a high current rating.
Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.
The insulation on STW and SJTW cords resists water.

Shielded Ethernet Cords
The shielding on these cords blocks signal interference from nearby equipment and devices. They send data between computers, printers, servers, and switches. For faster data transmission speeds, choose a cord with a higher ethernet cable category. They’re backward compatible, so they work in networks that meet the same or a lower category.

Continuous-Flex Ethernet Cords
Often used in automated applications such as robotics, these cords withstand continuous motion without degrading data transmission. The shielding blocks signal interference from nearby equipment and devices. They send data between computers, printers, servers, and switches. For faster data transmission speeds, choose a cord with a higher industry designation category. They’re backward compatible, so they work in networks that meet the same or a lower category. All stand up to some abrasion.
Cords with polyurethane rubber insulation resist abrasion better and bend further than cords with PVC plastic insulation. You can use them indoors or outdoors, though you shouldn’t use them in harsh settings. They’re halogen free.

Duct-Rated HDMI Video Cords
Run high-definition signals through duct, above drop ceilings, and below raised floors without using conduit. These cords are plenum rated, so their insulation resists fire and doesn’t produce smoke. Connect these cords to monitors, TVs, and projectors. Each end has both an HDMI plug and a micro-HDMI socket, so you can connect multiple devices to the cord at once. The plugs are gold plated to resist corrosion and maintain signals over time.
Note: These cords only transmit signals in one direction. Ends are labeled “Source” or “Display” to help you install the cord.
