Fits perfectly. I use it with my EPX-325S GBS.

I don't know exactly, but I think so. I bought a Spirit II E-210 GBS and it fit very well. Both are very similar in their dimensions, so I think it will fit well.
However, I had to wait almost a month for it because the Liferant (Weber) had shortages.
The bonnet is simple but very practical, good quality, and recommended.
So "the Weber" doesn't get dusty in summer and not cold outside alone in winter ;-)
