This is a pretty good barbecue access door. I think I should have gotten a bigger one because it is just barely big enough to get a 20# propane tank through. I did have a problem installing it in a stuccoed block wall because the inside attachment holes were not long enough. I wound up notching the stucco o fit the frame and then also using clips to hold the door and mounted the clips into the side of the block (8x8x16"" cinder blocks). I also added some screws and fender washers for insurance (typical overkill for me).
