There are many products that Grin has designed 100% in house, and which we either manufacture fully ourselves or with the assistance of other facilities. These are our “Grin” branded products which we try to make best in class, with full documentation, support, and long term warranty.
Over the course of Grin’s history we have also had several products run their course and get retired. In some cases this has been because they have been superseded by better technologies, and in other cases it's because of supply and production issues. We maintain these old product pages for historic reference.
