This is the official replacement classic flare foot with an extra-wide 5.25-inch base. It’s made to be used with Grav Labs’ STAX modular water pipe. The Flare Foot Base comes with an included removable 18.8mm to 14.5mm diffuser downstem as well as a 14.5mm male herb bowl and measures 8 inches in height. You also get one plastic keck clip and one metal keck clip. The base itself is made from top-quality borosilicate glass and decorated with the iconic STAX decal. It sports an 18.8mm female ground joint. This resilient and robust glass base is the perfect replacement or spare part for the STAX modular water pipe. Truly great craftsmanship - as you’d expect from Grav Labs.
