Sneaky Pete says:
When the heat is on, you want the MiniNail Heater Coil Guard on the job. Avoid the potential for burns or accidents by creating a buffer around your heater coil. The high quality stainless steel guard reduces the heat, and fits nicely between the heat spacer and male/female adapters on all models of the MiniNail Hybrid Nail.
One note: this will not work on Quartz e-bangers.
