• Precise Adaptation: The plug cover accurately matches the size and shape of the 3-pin plug, and is compatible with the American standard three-pin plug. It can fit seamlessly to ensure the protection effect and good versatility.
• Product Parameters: The package includes 2 3-pin plug protective covers with an overall length of 5.9 inches, which tightly cover the extension harness to ensure that your engine block heater can always operate normally in bad weather.
• Convenient Installation: The protective cover adopts a snap-on design. When installing, you only need to align the protective cover with the plug and gently snap it in. No tools are required, and the operation is simple and quick.
