There will be a clamp that clamps the rail and has 3/8-16 bolt to mount on to a tripod. That looks like the item on the left of the picture in front of the recessed lens baord. The rail is clamped by that and to the tripod head. both the front and rear standard also clamp to the rail (the front standard holds the lens, and the rear standard holds the ground glass and film.)
It looks like included is a number of rail extensions. the longer the lens the more distance you'll need between the standards, so you'll potentially need to attach the extensions in order to get enough distnace.
Give the weight of the camer you will want a pretty heavy duty tripod and head. You may even want to skip using a head and just adjust using the tripod legs. My 8x10 tripod is a Gitzo 5 series, and is the low-profile 3-way head I use. The are sufficient for a Toyo 8x10 field camera, but that is lighter than what you have.
