What it is

The Comnova Grill Cover is a robust alternative to expensive brand name accessories, specifically engineered to shield the Weber Summit 400 series and select Genesis models. Constructed from high density 600D Oxford cloth, this cover avoids the common pitfalls of cheaper PVC alternatives which tend to crack and stiffen in freezing temperatures. The PU coating provides a flexible, waterproof barrier that remains breathable, significantly reducing moisture buildup and rust risk for your expensive stainless steel investment. Beyond basic water resistance, the fabric is treated with a UV resistant coating that has undergone rigorous aging tests to ensure it won't fade or become brittle after a season in the sun. The design includes wide adjustable Velcro side straps that allow for a custom fit, preventing the cover from parachuting or sliding off during high winds. It offers a precise silhouette that mimics the original manufacturer design at a fraction of the cost, making it a pragmatic choice for year round outdoor storage.

Ravvy AI insight

While marketed for the Summit 400 series, the 66.8 inch width makes this a versatile fit for the 2022 Genesis S-325s as well. The transition from PVC to PU coating is a critical technical advantage here, as it prevents the material from cracking in cold climates. Always ensure the side straps are tightened fully to prevent friction wear against the grill corners during windstorms.

How to get the most out of it

Securing for Wind

Use the adjustable side Velcro bands to create a snug fit around the base of the side tables. This prevents wind from getting underneath the cover and creating a sail effect that could tip the grill.

Ownership tips

care

Wait for the Cool Down

Always wait at least 15 minutes for the grill to cool before applying the cover. Placing the fabric on a hot cookbox can melt the interior PU coating and damage your grill's finish.

tip

Preventing Surface Mold

While the cover is breathable, it is wise to remove it every few weeks during humid months. This allows trapped condensation to evaporate and prevents any potential mold growth on the grill exterior.

Frequently asked questions

Will this fit the Weber Summit 600 series?

No, this specific model is designed for the 400 series grills. The Summit 600 series is significantly wider and will require a larger cover size to fit properly.

Is the material actually waterproof or just water resistant?

The 600D Oxford cloth is backed by a PU coating, making it highly waterproof. It is designed to shed heavy rain and snow without allowing moisture to penetrate through to the grill.

Can I wash this cover in a washing machine?

It is not recommended to machine wash the cover as it can damage the PU and UV coatings. Instead, simply spray it down with a garden hose and wipe with a soft cloth for best results.

How does the PU coating compare to PVC?

PU or Polyurethane is generally more flexible and eco friendly than PVC. It does not emit strong chemical odors and is less likely to become stiff or crack when exposed to freezing temperatures.
