GenTent XL Open-Frame Generator Cover — Extreme Slate, Fits 105–128" with Tool-Free Clamps & Access Door

GenTent XL Open Frame Running Cover is a weatherproof, fire-rated canopy and clamp kit built to let larger open-frame portable generators run outdoors safely in rain, snow, and wind while preserving airflow and access.

When you need to operate a big open-frame generator in adverse weather, the GenTent XL (Extreme, Slate) provides a purpose-built shield that keeps electrical components dry, maintains proper exhaust and cooling clearance, and fits a wide range of large units without permanent modifications. The Extreme edition adds enhanced UV and cold-weather resistance for harsher climates, and the universal clamp system installs tool-free so you can set it up quickly and securely.

How does the GenTent XL protect a generator while it’s running?

The canopy uses waterproof, water-shedding vinyl engineered to route rain and snow away from sensitive components while keeping exhaust and airflow unobstructed. Materials are dual-coated and meet NFPA 701 and UL V-0 flame-retardant standards for safer operation around heat sources.

• Waterproof, dual-coated vinyl canopy diverts moisture from electrical areas
• Patented airflow profile preserves cooling and exhaust paths
• Flame-retardant materials reduce ignition risk near hot engine parts

Will it fit my large open-frame generator?

GenTent XL is designed for perimeter dimensions between 105 and 128 inches and uses a universal clamp system that secures to most open-frame footprints without drilling or permanent changes. The clamps hold in place through wind and vibration while allowing you to remove the canopy when not needed.

• Fits generators with perimeters from 105" to 128"
• Universal clamps attach without tools or permanent modifications
• Stable mounting system resists dislodging in high winds

How easy is it to use during long runs or refueling?

The XL model includes a large access door sized for safe refueling and routine checks without removing the entire cover. The design prioritizes operator access and ventilation so you can maintain fuel and fluid levels while the generator remains under protection.

• Oversized access door lets you refuel without removing the canopy
• Engineered clearance keeps cooling unobstructed during operation
• Tool-free clamp adjustments speed installation and removal

Is the Extreme edition durable in sun and cold environments?

The Extreme (Slate) edition adds enhanced UV treatment and extended low-temperature ratings compared with the Standard model, helping the canopy resist fading, cracking, and stiffness in prolonged sun exposure and subfreezing conditions. All core safety and airflow features remain the same across editions.

• Enhanced UV-treated vinyl for longer outdoor life
• Improved cold-weather performance for extended low-temperature use
• Same engineered airflow and safety standards as the Standard edition

Who is this for: The GenTent XL Open Frame Running Cover is suited for contractors, event production teams, emergency preparedness coordinators, and homeowners who run large open-frame portable generators outdoors in challenging weather. Choose this model when you need a robust, non-permanent protection solution that balances weather defense, operational access, and safety-rated materials for longer outdoor deployments.
