A very cool add-on for Spike's conical line. Spike heard many brewers who have switched from clear carboys to stainless and they only have one complaint; They couldn't see their beer fermenting any more. Spike's engineers designed a clear polycarbonate (same material as bullet proof glass) cap which allows you to see inside the top of the conical when it's fermenting. This has also been tested against common brewery chemicals and has held up against the likes of PBW and StarSan. Specs: -4" TC -Clear polycarbonate material
