this is a must have to protect the griddle surface and to keep it clean between uses. the reinforced corners are a great idea and it accommodates the surround with out having to remove it and store it separately. i use an inverted full size foil pan to stop it from sagging and touching the griddle surface and the clips underneath keep the cover snug.
The cover is waterproof but where the griddle is so flat and has no shape it can build condensation underneath the cover if you do not “tent” it. I have an old volleyball under my cover lifting it slightly off of the griddle. My griddle is outdoor year round in the rain and snow and with my seasoning I have built up on the top and the tented cover, I have never had a problem with rust.
After buying my 36" Griddle I purchased the 36" Griddle Cover. This cover works and fits perfectly over my griddle and looks great in my backyard. I did take the suggestion of tenting it and have not had a problem. Thank you Blackstone!
