The GRAV Classic Steamroller is a minimalist glass device engineered for dry herb consumers seeking substantial pulls and a clean aesthetic. Crafted from heavy-wall borosilicate glass, this seven-inch piece utilizes an uninterrupted tubular design that allows for rapid vapor accumulation. Originally conceptualized by designer Dave Daily, the device integrates practical solutions to common user pain points, such as ash inhalation and surface instability. It appeals to users who appreciate scientific glass construction combined with straightforward functionality. With its durable build and thoughtful engineering, the piece delivers a highly controlled and mess-free experience for daily dry herb consumption.

Uninterrupted Tubular Design

The body is constructed from a single piece of heavy-wall borosilicate glass. This straight, 25-millimeter diameter tubing facilitates rapid vapor accumulation for substantial pulls. By utilizing a continuous cylindrical shape measuring approximately 181 millimeters in length, the piece maintains a sleek, modern aesthetic while maximizing internal volume. This scientific glass approach ensures both durability and consistent performance over time.

Inverted Ash-Catching Mouthpiece

To prevent debris from reaching the user, the device features a proprietary inverted cone mouthpiece. This specific internal geometry acts as a mechanical filter, trapping unburned material and ash inside the chamber during inhalation. By keeping the mouthpiece area completely clean, this built-in ash catcher eliminates the need for secondary screens or filters, providing a mess-free draw every time.

Stabilizing Glass Roll-Stops

Addressing the tendency of cylindrical objects to move on flat surfaces, the design incorporates two built-in glass feet near the bowl section. These integrated roll-stops create a secure resting base, allowing the steamroller to sit flat and remain stationary on tables or counters. This simple physical addition protects the heavy-wall glass structure from accidental falls and damage.

Raised Bowl and Carb

The top of the cylinder features a deep, raised fixed bowl that provides ample capacity for dry herb packing. Opposite the mouthpiece, a large front-facing carb hole offers precise manual airflow control. This configuration allows the user to easily regulate the draw resistance and instantly clear the 25mm glass chamber, ensuring consistent and highly controlled usage.
