For what its worth. I have a 20 Long and the 12 1/2" width includes the top lid support.
Actual glass is only 12 1/4" wide minus 1/2" for glass edges leaves you only 11 3/4"
Also distance between top supports is only 10 7/8" .You could probably trim back lid
support to be able to use the full 11 3/4". Hope this helps
