The TVR-2160C Stack Quad Coupler is an adapter that was added in version 0.21 in KSP. The Quad Coupler is useful in some ways, tying with the TVR-400L Stack Quad-Adapter for the dedicated adapter with the most outgoing nodes. It is typically used to separate a single size 1 (1.25 meter) stack into four separate stacks. It supports fuel crossfeed.

The quadcoupler has non-standard (0.3 instead of 0.2) drag, meaning it should be placed behind the center of mass to ensure stability. Given its intended function, this can be problematic.

Product description

What could be more awesome than a Tricoupler? Why, a quadcoupler, of course. Just remember that this is not a decoupler, and will not separate stages.
