The Upline® ash catcher is 5" tall and made on 38mm tubing. Its ladder perc restrictions create bubbler chambers that wash and filter smoke. Its showerhead downstem diffuses smoke through water and is fixed inside the ash catcher to prevent damage. Its 90° angled arm is designed for use with a 14mm female joint on any straight-based water pipe. The Upline® ash catcher comes ready to use with a 14mm Octobowl and works best with approximately 2" of water.
