When you need a flexible extension cord, a rubber one can be a great solution. Rubber extension cables are made with TPE rubber for exceptional flexibility and strength. They are flame retardant and are resistant to oil, moisture and ozone. They also feature a powerful Primelight power indicator light, which lets you know when power is running through the cable. They also have oil-resistant inner conductors and durable jacketing.

Depending on the purpose of the cord, some cords may have special markings or features. Some may be temperature-rated up to 75 degrees Celsius, water-resistant, or have a usage designation like "FOR MOBILE HOME USE." Other types of cords may have designations like "Extra Hard Service," "SE", or "SO". These cords are designed to be rugged and withstand abrasion and crushing.
