The closest pivot pins for your Marvin window are 26-150 . Please compare sizes and see if our part will work.

the 26-150 pins are perfect for replacement of the cheap plastic pins on the Marvin Ultimate tilt back windows. I suggest you put these pins on the same page as all the others as I only found them through the 2017 chat. You all provide great service.
