What Cokin X Pro filter ring for a Schneider IVB center filter please?

[newmoon2night]

I'm planning on getting a Cokin X Pro filter holder to attach to the Schneider IVb Center Filter.
Does anyone know what filter ring I should order?
It will be 112mm diameter, but the Cokin rings seem to come in different thread sizes also.

As you can see here (http://www.schneider-kreuznach.com/pdf/foto/centerfilter.pdf) it's M 112 x 1.5
