We went with the true Blackstone cover for our griddle after purchasing a competitors cover, which turned out to be faulty and not waterproof. We use a shallow 30" plastic bin placed upside down on the griddle top, after it cools of course, then cover. The tenting assists with prevention of condensation pooling on the griddle top. Love this cover!
Love this grill cover! Great quality, perfect fit and love how well it protects the flat top along with the sides of my griddle. Great protection as I keep it in my garage with very little room to move things around.
My griddle/grill is awesome and it's covered by the best... it's matching cover. All my friends ask, "what's under that cover." Then I unveiled to reveal my grill/griddle to my guest's exclamation, "WOW is that cool." My reply? "Actually, it's about to get very hot. Pancakes and eggs for breakfast folks."
