We used it for a Big Green Egg large, so there would be no problem using it for a Jr. We placed Concrete paver tiles underneath to protect the wood against the heat, you will likely need to put a couple of them to raise the grill two serving height because I believe the Jr is a smaller grill. I hope I answered your question and good luck
Yes, the diameter of the cutout is 22.5 inches.
It can be altered to work if necessary.
Nope. Fits my large barely.
Yes it can
The hole is very large but my grill is very small. I believe the hole measurements are in the description. I cannot measure it now that I have my cooker in it. Yes did like that the second shelf that the cooler sits on is adjustable I have it in the first from top bolt hole. Since mine is so much smaller than most of them.
Oh yes that is what I have and plenty of room for it but I did have to remove the holder with handles it comes with. I just had someone help me put it in the hole.
I am not familiar with the Big Green Egg grill as I mounted a standard Weber grill. However grill opening is 23 inches in diameter and maximum distance between top horizontal surface and lower horizontal surface is 18 inches. Also, you need to mount grill so it is not in direct contact with any wood surfaces. I used electrical conduit clamps to hang grill
It all depends on what style grill and what cement block you underneath the grill to sit it on. As reference, this table fits most large size egg-style grills, and even some XL sizes for certain brands. It's typically an issue of how big the grill can be to fit in the pre-cut opening, versus the actual weight.
Yes, a 22 inch kettle grill fits the opening. I don't know if the tabletop is sold separately. Check with HD.
