This is essentially a labor charge item to add a 1.5" or 2" TC port to any SPIKE blank slate custom kettle. This item should only be added to a cart that has a Spike custom kettle in it. You must specify positioning and whether it is for a 1.5" or 2" TC port. Keep in mind that a 1.5" TC has an actual flange measurement of 2" and a 2" TC measures 2.5". This is the price SPIKE charges to weld in a TC port when we're ordering it directly from Spike.
