I had a request to provide some measurements on the Weber 18.5 inch One Touch Silver. I thought I would go ahead and post them here just in case anybody else was interested.
From the bottom of the kettle to the charcoal grate is 3 inches.
I measured the diameter of the charcoal grate as 14 inches.
The distance between the charcoal grate and the cooking grate is five inches.
The cooking grate rests 1.5 inches below the edge of the kettle.
The diameter of the kettle is 18.5 inches.
And the distance from the cooking grate to the top of the dome is 5.5 inches.
I hope this information is helpful. If you would like to see some different pictures or need different numbers please let me know.
