These are quartz bangers made by Eric Ross with a pin boss attached to the bottom for securing the coil with a pin. The nails have a 24mm outer diameter with 2mm thick walls. Nail with coil and hardware is included in this combo set. Option for just the nail will be available.
Coil has 5-prong standard XLR connector compatible with EZBake, Dnail, and Pelinail controllers. These coils are guaranteed ONLY in when used with these company’s controllers. Other controllers are wired differently and are subject to shorting out the coil. ONLY USE EZBAKE, DNAIL, OR PELINAIL CONTROLLERS.
