Enhance your dabbing experience with the GRAV Control Tower Banger Set! Constructed from premium quartz material, this banger has a beveled top edge compatible with the marble style carb cap. The banger's thick bottom dish ensures lasting heat retention and the fully welded, seamless joint promotes longevity no matter how often you dab. The elongated bucket has three directional slits for air intake, creating a vortex that spins the pillar insert to stir melted concentrate and promote even vaporization. Each banger has a 14mm male joint connection size and a 90 degree joint angle.
