This is a mechanical bottom insulator that will adapt your existing Hercules 3.7/7.4, Hercules SR-71, SR-74, or SR-74x with native 601 threading (on the Threaded Assembly) into a 510 threading for compatibility with variable power box mods. This adapter is for native 601 Hercules only and will not fit on a 510 threaded Hercules.
This insulator has two o-ring grooves for compatibility with the Nibbler XL Bubbler.
It features a user adjustable pin that requires proper and occasional adjustment for to ensure connectivity: Hold one screw and turn the other 90° counter-clockwise, check and repeat if necessary until contact is made.
It's subject to wear and may require replacement if the Hercules has been repeatedly overtightened.
