The truck carries the parts that cover most calls - standard torsion springs, standard-width rollers, common cable sizes, universal opener logic boards. Those cover the majority of Red Lion doors just fine, because plenty of 1944-era garages have already been re-fitted with modern-width doors at some point in the last few decades. What we don't carry on the truck is anything sized to an original, never-upgraded 1940s opening - odd-width track, non-standard spring wind, obsolete hinge patterns. If that's what's on your garage, the first visit is a measure-and-order trip, not a same-day fix, and we'll say so before we start the clock.
