In this video I show how to troubleshoot Blum undermount drawer glides that are a loose and rubbing against your drawer box. #mtkc #blumdrawerglides #undermountdrawerglide
I have seen this from time to time in the past. I don't know how this happens exactly, but one theory that I have is the drawer glide hardware is no longer as strong as it used to be when it was new. Short of a drawer glide replacement, I think you can tweak and shift the drawer glide mounting point a little further recessed into the cabinet box itself as an alternative workaround. I hope that is sufficient. Are you still within warranty for a new set of glides?
