Kingpin Cooling Extension Kit for F1 Series CPU Containers, Black

The black anodized aluminum extension kit is compatible with Dragon F1, F1 extreme, F1 Gemini, and F1 Dark cpu units. This extension makes the container perfect for full-pot Ln2 benching when temp control is not an issue. The kit is also great for dry ice use as it nearly doubles the internal volume of the unit requiring less time spent filling and packing the container and more time benching.
