Overview
The Unicook B63-018 steps up from the standard mid-size offering with a 60 x 28 x 38.5 inch profile that fits larger four and five-burner gas grills. The vinyl-coated polyester construction improves on bare polyester by adding a water barrier that prevents rain from soaking through to the grill surface.
At 60 inches wide and 28 inches deep, this cover accommodates the broader footprints common on larger gas grill platforms with extended side shelves. The black colorway is straightforward and matches virtually any grill finish.
With 1,200 reviews at 4.7 stars, buyer feedback is solid for a cover in this larger size category. The combination of correct sizing for big grills and vinyl-coated construction makes this a practical, well-regarded choice for backyard setups with full-size gas grills.

Performance notes
The vinyl-coated polyester used in the B63-018 provides reliable rain protection and is easier to wipe clean after storms than uncoated fabric. At 60 inches wide and 28 inches deep, this cover reaches beyond the typical 55-inch standard, handling the extra width of larger gas grill platforms. The 38.5-inch height is proportional for most freestanding gas grills with their lids closed.

Frequently asked questions
Will this cover fit a four-burner or five-burner gas grill?
The B63-018 measures 60 x 28 x 38.5 inches, which accommodates most four and five-burner gas grills. Before ordering, measure your grill including side shelves and handles at the widest and deepest points to confirm the cover will drape properly without being too loose or too tight.
How does the vinyl coating hold up over time?
Vinyl coatings provide strong water resistance for several seasons under typical outdoor conditions. Over many years of sun and temperature exposure, vinyl can begin to crack or peel, particularly in climates with severe cold. Storing the cover out of direct sun when possible helps extend its lifespan.
