True Bulkhead from Brewhardware.com

[thunderwagn]

I'm converting a Coleman cooler to a mash tun and looking to buy one of Bobby's bulkheads for the project. I use several other parts from brewhardware so I know the quality is good. What I can't find however on the website is the length of the shank/threaded nipple that would pass through the cooler. If anyone has one and knows the length, I'd appreciate it!
