https://www.ebay.com/itm/163553963821" onclick="window.open(this.href);return false;" rel="nofollow this is the link I used to receive my 65l stainless steel lid not available in the United States. With the exchange rate and shipping was still less than what they will charge when and if they become available. 16 inch lid from Australia. They carry alot of cool stuff not way over priced like here. And they will combine shipping.
I have the 35L version which I presume is pretty much the same thing.
The lid is definitely strong enough to support the reflux column, and I assume the other one they offer. It's attached to the lid by screwing on a large nut like thing on the other side of the lid. It holds it in place solidly enough for me to hold it horizontally and not to get any flexing. The reflux column is 490mm tall, and maybe 60mm diameter.
It's well built, sturdy and all the joints look clean. I have zero complaints about the one I have.
Keggland will not ship to the United States directly that's why my link with strength of the dollar I saved .37 cent to each dollar and it only took 4 days for me to get it in Florida. Lid is very solid and strong enough for a two or three inch column and is 16 inch with a good high temp gasket. Center hole is 48mm
