That's what I was hoping for.
I've been using some Walmart covers
I got on clearance for $2.
They fit the 18 and 22 fine
and can be made to fit the 26
with a little persuasion but
they get a bit stretched and will tear.
They really are junk but for the $, meh.
Bought a bunch of other sizes 50 ,55, 65 and 75
at Walmart as well for $5 to $8 and some of them
are really not that bad.
My goal is to get Weber covers for everything.
