4x5 Graflok Dividing Back by Graflex is in reality Graphic, the same like Singer Graflex RH-50(67/70mm)- learnt from these links

they have both two ridges. one of them will fit into the single grove on the camera-back. second one touching the outer end of the frame.
So what will be the problem when trying to mount these on Graflok-back cameras?

Michael, you have it completely backwards.

Film holders that fit Graflex (as in Graflex SLR) backs have a slot that mates with the lip of the Graflex back's gate.

Film holders that fit Graflok backs have two ridges that mate with a groove in the back at the right edge of the gate and with the right edge of the back.

To learn about the RH-50, go here: http://www.butkus.org/chinon/graflex/graflex_xl/graflex_xl.htm

To learn about the dividing back, go here: www.galerie-photo.com/manuels/pacemaker-crown-speed-graphic.pdf and see p. 38
