The Mason RDA offers dual tiered, focus directed airflow straight to the coil with a variable triple tiered air flow control ring. Staying true to the uni-post deck design, the negative posts are dug out leaving more room for coils and cotton configurations.
Square center post in a square hole in a square peek insulator in a square deck hole ensures no spinning or loose connections. The delrin insert in the top cap is threaded for added convenience, allowing the user to replace and remove the insert for replacement or chuff upgrades. The extended 510 connection keeps this rda safe on any mod, even if it's a hybrid. The unique heat sink built into the top cap also echoes the brick mason theme, as does the overall packaging of this rda.
