Searching for a nail that fits a 14mm dab rig? What about 18mm? Why not both? This 2mm domeless quartz banger nail is built to fit a 14mm AND 18mm joint without any complex setup. The nail is available in both male and female as well. Just like all banger nails, this nail has a bent tube that moves the heat of your torch away from your vapor rig to prevent heat stress and premature cracking on the joint. The nail uses an open dish where you place your concentrates. The design of this banger quartz nail provides spacing from the dab rig, extending the life of your rig by preventing breaking that can occur when you heat directly on the joint. This domeless banger nail is made of high quality quartz and is a great additional accessory for your dab rig.
