What connectors come with MFS extension rails?

[Stoli]

I have an MFS400 set, and am looking to purchase a pair of MFS1000 rails (492725).  I am hoping to join these rails to the 200mm rails from the MFS400 set to make a long, narrow MFS.

I can see in the description that the rails come with "connectors", but can't figure out if these are connectors to make a rail longer (parallel connectors, probably P/N 493235) or to allow a right angle connection (perpendicular connectors, the ones with an outside thread with a screw inside that you need to use the ball driver to tighten). 

Does anyone know what kind of connectors come with the rails?

If they are the parallel kind, does anyone know the EKAT P/N for the perpendicular connectors so I can order them separately?

I don't know this for sure, but I believe the long MFS extensions come with both types of connectors.  Someone please confirm.

I have bought a couple of additional sets of connectors (1000mm and 200mm) and both sets came with the connectors to connect at right angles (installed) and they also came with 8x straight connectors each (2x 493235).

Thanks Brice and Ed!

For completeness, Ed and Brice were correct.  I just got my MFS1000, and it came with the right angle connectors installed, plus 8 straight connectors.
