The flat coil works with all High Five Titanium Nails and Quartz Hybrid Nails. The flat coil heats the bottom of the nail directly where your concentrates are placed for optimum heat transfer and improved vaporization.

*WARNING*

While High Five coils may fit your unit and vice versa, internally wiring may not be compatible. It is recommended you confirm that the wiring is the same if attempting to use a High Five coil with a different branded controller.
