GRAV Quartz Control Tower Banger – 14mm 90°

This banger has a 14mm male joint at a 90-degree angle, which fits any dab rig or water pipe with a 14mm female 90-degree joint. The 14mm size is the most common joint configuration found on standard dab rigs and straight-base water pipes, making this banger widely compatible. Always verify both the joint size and angle on your rig before purchasing to ensure a proper fit and correct bucket orientation.

The GRAV Quartz Control Tower Banger 14mm 90 is the standalone banger only and does not include a carb cap or terp inserts. If you want a complete set with a 20mm quartz marble and terp pillar insert, the GRAV Quartz Control Tower Banger Set 14mm 90 is available separately. The standalone banger is a good option for those who already own compatible terp accessories or prefer to build a custom setup with their preferred carb cap and inserts.

The bottom-loading intake is a small opening at the base of the dish that allows you to place concentrates directly into the lower chamber of the banger from below the cylindrical body. This is especially useful with the tall Control Tower design, where reaching over the top edge to load a dab can be awkward. Loading from the bottom positions the concentrate at the base where heat is most concentrated, improving vaporization efficiency and reducing the chance of spilling concentrate during loading.

A directional bubble carb cap or a flat marble cap that sits properly on the top of the cylindrical opening works best with the Control Tower design. The 20mm quartz marble included in the Control Tower Banger Set is an ideal match. The cap should create a reasonably airtight seal to allow the three directional air intakes to generate the rotational airflow pattern the Control Tower is designed for. Avoid large directional caps with an opening diameter significantly larger than the cylinder top.

Yes, the elongated cylindrical chamber of the Control Tower Banger is designed with enough internal volume to accommodate terp pearls of standard 6mm size. The three directional air intakes will spin the pearls inside the chamber during inhalation in the same way they rotate a terp pillar. Using terp pearls instead of a pillar provides a different surface area pattern and is particularly effective for smaller concentrate portions where maximum surface contact with the quartz walls is desired.

Heat the base of the dish and the lower portion of the cylindrical body with a torch until the quartz becomes visibly hot, then allow it to cool for 45 to 60 seconds before loading your concentrate. The thick gathered dish base retains heat well, so avoid overheating the banger. A digital thermometer or infrared temperature gun can help you monitor the surface temperature. Most concentrate enthusiasts find that a bucket temperature between 450 and 550 degrees Fahrenheit produces the best balance of vapor output and flavor preservation.
