The Fine Print

All of the final assembly is done in the US and almost all of the parts come from the US. As one example of the parts distribution, for our 2511 snap disc thermostat line: Of the twelve components, one part comes from South Korea and another from a vendor that just moved their production to India. The other ten parts are either made in-house or supplied by a US manufacturer. This works out to around 2% of the total cost from overseas parts and 98% of final production and first level fabrication done in the US. That said we have a number of very good vendors from other countries that do a great job.
