Yes just the base. BTW I have been supplying Rutland gaskets to fellow eggers since 2002 and to date have sold 1,219 of them. I break even on my service. I also provide instructions on how to properly remove the old gaskets and how to apply the Rutland...neither ACE or Amazon does that...my charge due to postage is $11 for a large or $13 for an XL. If I ship to Canada the price is higher due to postage being triple what US rates are.
