If you have questions about your specific model, contact GenArmor customer service for confirmation, as they are known for responsive support and helpful guidance.

Installation Considerations:

Plan for approximately 30 minutes of assembly time in a workspace where you can lay out all components. All necessary tools are included. The cover requires a designated outdoor location where it can remain installed. For generators that run frequently under heavy load, plan to lift the sides for ventilation to prevent heat buildup.

The GenTent Original is a specialized weather cover designed for homeowners, contractors, and property managers who need to run portable open frame generators outdoors during inclement weather. Unlike standard tarps or basic covers, this product is engineered specifically for operational use, meaning your generator keeps running while protected from rain, snow, and harsh elements.
