We use Vanstone flanges whenever it is requested by the customer. It is usually in older existing installations. We use rod extension kits so these rods can be made into any length needed for the application. These allow for the extension and then addition of other extensions to them.
PART NUMBERS for Sensor Tip Extensions
(extensions come with both ends threaded allowing for additional rods to be added as needed)
All Sensor rods are 45.5 inches long.
