E-nail

An e-nail is an electronically heated nail assembly that replaces the butane torch in a traditional dab setup. A coiled heating element wraps around a titanium, quartz, or ceramic nail and is driven by a PID controller — a temperature regulator that maintains a set value within a few degrees by cycling power on and off. The five-pin XLR connector has become the common wiring standard. Typical operating ranges span 300–1000°F, with roughly 510°F favored for low-temperature flavor dabs and around 710°F for larger-vapor high-temperature dabs. Coils are sold in 16mm, 20mm, 25mm, and 30mm diameters to match nail geometry. Solid-state relays have largely displaced older mechanical-relay controllers because they cycle silently and degrade less over time. E-nails retrofit onto standard glass dab rigs and offer two advantages over torch heating: precise, reproducible temperatures and the ability to take back-to-back dabs without reheating. They are distinct from e-rigs, which integrate battery, water chamber, and heater in a single portable unit. → See also: E-rig, Banger, Dab. ---
