Steel folding clasp for 20 mm wide straps?

I wonder if there is a 20 mm wide (I mean to take straps of 20 mm at the clasp) folding clasp available in steel? (I know about the titanium but at that time the widest steel folding clasp was to take straps of 18 mm width at the clasp.)

If yes the ordering IW code would be also nice to know.

Thanks a lot in advance!

Robert

Hi Robert

I know there is a 16mm and 18mm deployant. 
Good question regarding 20mm. Would be interesting to know.
