Yes. I drilled quarter inch holes through the shell and internal supports midway between the bottom and top grate supports. I put 1/4" x 1/2" bolts in those and they support a standard 18" grate (same as the top grate or the grate from an 18.5 kettle.) It's a tight fit in the smoker and takes a little maneuvering to get in place but aside from that it works fine. Other options include supports from the bottom grate or hanging from the top grate but I'm happy with short bolts through the shell.
