The ProTeam 103181 is a complete 18-foot, 14/3 power cord assembly with strain relief for the Sierra backpack vacuum. The strain relief fitting protects the cord-to-unit junction from flex fatigue — the most common failure point on commercial vacuum power cords under daily use. This is a complete assembly, ready to install without additional hardware. Built for commercial use and compatible with GoFit 3, GoFit 10, GoFree Flex Pro II, GoFit 3 Cordless 4Ah, and more than 23 additional ProTeam backpack vacuum models per the source listing.
