The Opal Starlight Control Tower Cap is our hands-free carb cap made from frosted glass with a stunning UV-reactive design. It creates a perfect vortex for low-temp dabs and fits standard 25mm bangers.
This is an advanced dabbing accessory we designed for precision and style. Made from frosted borosilicate glass, it blends a beautiful UV-reactive galaxy print with top performance. Its main job is to manage airflow over your heated banger, creating a vortex that spins concentrates and terp pearls for efficient and flavorful vaporization. The unique control tower design and secure clamp lid offer a more hands-off and effective dabbing session, especially at low temperatures.
A control tower carb cap creates a controlled vortex of air inside a quartz banger. This spinning airflow, called an auto-spin feature, distributes heat and moves your concentrates. This gives you more complete vaporization at lower temperatures, which saves flavor and gets the most from your material. It's the perfect tool for anyone who wants great flavor and efficiency without having to manually move the cap.

The details make all the difference. Here’s a breakdown of what makes the Opal Starlight Control Tower Cap work so well.

|---|---|---|
| Control Tower Design | A structure with angled air intakes at the top. | Makes a powerful, hands-free vortex for even heating and maximum vapor. |
| Clamp Lid Mechanism | A built-in latch that secures the cap to the banger. | Stops the cap from falling off, ensuring a consistent seal and protecting your banger. |
| Frosted Borosilicate Glass | High-quality, durable glass with a matte finish. | Offers excellent heat resistance and durability, while the frosted texture hides fingerprints. |
| UV Reactive Galaxy Print | An artistic glass insert with patterns that glow under a blacklight. | Looks amazing and glows under a blacklight, making your setup impressive in low light. |
Beyond the basics, several design choices make this carb cap a standout piece. From its automated airflow to the secure latch system, every feature is made to improve your dabbing experience.
The auto-spin function works using directional airflow. Air is pulled through two angled holes at the top of the "control tower." This creates a swirling vortex inside the banger. This spinning air stirs your concentrates and spins any terp pearls, ensuring no material is wasted and everything is heated evenly for a smooth, consistent hit.
The integrated clamp lid, or latch, is a great feature for stability. Unlike standard caps that just sit on top of the banger, this mechanism allows you to securely fasten the cap in place. This prevents it from accidentally getting knocked off mid-session, which could waste your dab or break the cap. It guarantees a perfect seal every time for optimal pressure and vapor production.
The cap features a stunning galaxy-inspired pattern suspended within the glass. This isn't just for looks; the materials used are UV reactive, meaning they glow vibrantly under a blacklight. This adds a captivating visual dimension to your setup and turns your dabbing session into an impressive display, especially in a dimly lit room.
Follow these six steps for the perfect low-temp dab with your Opal Starlight Control Tower Cap.

Proper maintenance will keep your Opal Starlight cap functioning perfectly and looking great. The frosted borosilicate glass is durable but requires specific care to maintain its finish and the integrity of the clamp mechanism.
For best results, wipe the cap with a cotton swab after each session to prevent heavy buildup. For a deep clean, soak the cap in an isopropyl alcohol solution for 15-30 minutes. Use a soft brush to gently scrub any stubborn residue. Avoid abrasive tools that could scratch the frosted finish. Rinse thoroughly with warm water and let it air dry completely before its next use.
A few simple habits will extend the life and performance of your carb cap.
