The listing states a tough vinyl exterior for protection from sun and UV damage, rain, snow and dirt, an elastic base for a snug fit, and a design for 4800 to 11,500 watt generators that will also fit generators up to 30.7 x 23.6 x 23.6 inches. The spec table lists 28.7 x 23.6 x 22.8 inches, which reads as the cover's own size rather than the max fit, so trust the bullets for fit and the spec table for the cover size. It states a 1-year limited warranty.

Two contradictions need care: the title says 5000 to 15000 watts while the bullets say 5000 to 10000 watts, and the spec table lists 5.0 x 5.0 x 2.0 inches against the stated 32 x 24 x 24 inch size, so trust the title and bullets for size and treat the watt range as 5000 to 10000 watts.
