The GRAV® Ash Catcher is 5" tall and made on 38mm tubing. Its fission downstem diffuses smoke through water and can be removed for easy cleaning. Its 45° angled arm is designed for use with a 14mm female joint on any beaker or angled-based water pipe. The ash catcher comes ready to use with a 14mm funnel bowl and works best with approximately 1.5" of water.
