Discover the Thunderhead Creations Blaze BORO Bridge, a bridge designed for boro tanks to accept a single coil configuration with interchangeable airflow pins. Constructed from durable stainless steel, the Blaze Bridge is perfect for those who love to build, changing the interior of the boro system to accept a single coil within a half-pipe-shaped postless build deck. At the base is an interchangeable airflow pin, granting options between 1.2mm to 3mm wide openings.
