Question:
Do you carry a 7 round extension cord, or a 7 round female, female adapter to put two cords together. Need something like this for a semi truck to pull an grain cart. Thank You

Hi Tim; we don't have anything for a 7-pole round but I can give you the parts to make one. If you want female to female you will need two of the # PK11720 along with the Deka Wire - Jacketed 7-Wire # DW04914-1. The wire is sold by the foot so you can make it however long you need it to be. If you want a male end for one side to make a standard extension you can use the # PK11702.
