Coding of the buckle halves
We do not sell buckles like that, but informative how to interpret the inscriptions on the buckle halves:
If the second character after the color code (sixth letter) is M, it means the male half of the clamp, as in the photo the FY50_MV half designation from male-versatile.
If the second character after the color code (sixth letter) is W, it means the female half of the buckle, as in the picture the marking of the half of the buckle is FY50_WF - from women-fixed.
