The truck carries what matches Secaucus's own housing stock, not just the wider Jersey City-area average. That means standard-width extension spring pairs, safety cables to run through them, the common track rollers and end bearings that wear alongside a failing spring, and a stock of the mid-size opener logic boards that fit most 1980s-into-1990s residential units.
What we don't carry on the truck: obsolete opener boards for oddball or discontinued models from that same era, and full torsion conversion kits, which aren't a rush item since they're not what most doors here were built with. If a repair calls for one of those, we'll get the door safe and working that day and order the part rather than guess at a fit.
We're driving the 5 miles in from Jersey City for every call, so we load the truck for what a Secaucus door actually needs before we leave - that's the extension-spring-and-cable kit, not the torsion hardware more common in the older sections of the service area.
