The Beaker Double Stack is a perfect two stage big Prism piece. With three different levels of filtration, this thing pulls super smooth, but has a classic beaker look. Standing at almost 26", this piece is nothing short of massive, but you can easily break it down and throw it in a backpack for some exploring.
All together, this set up comes with a Standard Mouthpiece, the 7mm Classic Beaker Base, a 7 Stem Perc, a 12 Stem Big Perc, an 18mm joint, and then the downstem and bowl. It also comes with your selected aluminum clamp. The clamp is made of an aluminum exterior lined with a specialized rubber interior, along with a lever on the side to close and tightly seal the two pieces of glass together. On the interior of the clamp, there is a built in rubber gasket ridge where the two pieces of glass butt up against making a very safe and secure seal.
** For custom clamp combinations, please order your piece through the “Design Your Own” page **
