How they sell

Builds to order, so a purchase order buys a production slot rather than a unit on a shelf.

In practice that means a purchase order is a place in a queue. Ask for the lead time from purchase order in writing, and ask whether the quoted date is a ship date or a production start. Those are not the same thing and quotes rarely say which.

Where they fit on a job

Federal work needs TAA eligible origin, so confirm the country of manufacture on the specific unit rather than assuming from the brand. Many brands build in several countries.

If the lead time does not work

These hold stock, so they are where to look when the date will not move.
