As a manufacturer and a customer I can understand both sides of the coin. We put that our lead times are "approximate" and then add 12-14 weeks, because in our experience they have been done in about that or less. Things do happen though, and these are not off the shelf items. IT sucks when things are "late" but thats why we put approximate, because then we are in no way promising anything, just acknowledging that that is our typical lead time. They have a better lead time than us and most other fabricators though it seems. I do appreciate you thinking of us in your considerations and I dont know them personally but I know sometimes we get behind, steel shortages, vacation for fabricators, new product releases, machines going down etc etc. (You should still buy our sliders though)
