Buyer Beware

This cover does fit the 36" Slate perfectly, however, it is not as heavy duty as it should be. After going through a South Florida rainy season, the cover lost its waterproof protection. While covered, the grill still got wet. Being wet under the cover in hot weather led to "things" growing on the grill. Bought a no-name cover online to replace. Fit is not as good as the Weber cover but it is much more heavy duty and less than half the price. Weber - I'm sure you can do better.

Thank you for your feedback. We apologize for the disappointment with your griddle cover. Our covers are designed to allow moisture through, so it can evaporate away from the grill. In humid environments, we recommend only covering the grill during inclement weather. If you have any questions or concerns, please reach out to Weber directly so we can help!

Slate 36" Flat Top Cover

The cover for the slate 36" fits perfectly. The Velcro straps are a big help in windier conditions as well.

Your feedback is important to us! We're sorry to hear about the wrong griddle cover. Based on your photo of the box, the griddle cover you have is compatible with the 36" Weber Griddle and not the 36" Slate Griddle. We sincerely apologize for the incorrect cover provided. We are here to help. Please look for an outreach email from our Care Team soon. Thank you!

Does not fit newest 36" slate griddle

Does not fit the most recent slate! I purchased this cover with the 36" slate grill. Everything is great, except the cover does not fit. After folding a table which i should not have to do, it still wont go all the way and i can see the material ripping soon on the corners of the folded tray. Apparently this is a problem, because I'm seeing reviews stating the same thing.

Buyer beware, doesn't fit the most recent slate!

I purchased this cover and it's obvious there are probably 2 different versions with the same model number. The cover that I have doesn't fit the 36" slate. If I close one of the side tables I can sorta get the cover on but i's really stretched and doesn't go down to the bottom of the griddle.

Thin for the price

This cover is very thin for the price and should be a little loser fitting for ease of putting on.

BEST GRIDDLE EVER

Love how it cleans up and there is never no rust. The grand kids are amazed at how fast their breakfast is made since papa can cook it all at one time. Bacon is so crispy.

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We'll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.

This item leaves our warehouse within 10-14 Business Days

$49 Flat-Rate Shipping

Anything under $49 ships at one low price. If your order increases, your shipping stays the same!

30-Day Returns

Return all new, unused, and unassembled items in their original packaging, and we'll give you a full refund minus the cost of the original AND return shipping.

No Restocking Fee

Most companies charge a restocking fee. We just don't do business that way.
