How they sell
Holds inventory, so units can ship in days or weeks rather than months.
Stock is the reason to call them and price is the reason not to. A stocking distributor buys the same units everyone else does and carries the cost of holding them, so expect to pay for the speed. When your date is the binding constraint, it is worth it.
Where they fit on a job
CA origin makes this a candidate for federal and Buy American work, where TAA eligibility is a hard gate rather than a preference.
Common ratings
If the lead time does not work
These build to order, so they are where to look when the price matters more than the date.
