What are the dimensions of this cover and up to what dimension grill will it cover?

I am currently on vacation but this was the largest grill cover I could find. All of the other larger covers would not fit over the handle that sticks out on the left side of the grill. I purchased a jenne air grill and this cover is exactly as big as the original I returned many girl covers because they would not go over the handle on the side of the grill. This one did. Hope this helps it also has a front and back vent around its middle so moisture does not accumulate

What is the length of the cover?

I measured from the top corners at 6 ft. My grill is 69" including the grab bar on one end, and there is a few inches of slack. The couple inches of slack makes it easy to remove and replace the cover.I noticed on this cover, I have to use the velcro on each end to secure it, or the wind can blow it off. The OEM cover was tight enough that there was little chance of the wind removing it.

Is this going to fit a 6 burner grill with side burner?

Hello Amazon Customer, this cove fits grills up to 76 in. (W) x 26 in. (D) x 48 in. (H). Happy grilling!! Nexgrill

Curtis ... I'm unfamiliar with the measurements of the Nexgrill 700-0709N ... so just let me say, it's difficult to measure the cover itself ... but my bar-b-que measures 70" long x 24"deep x 50" high at its highest point (the middle section) and this cover fits with ample room and is tailored well to the shape of the BBQ. It's an extremely durable product and very easy to manage. Hope this helps.
