Don't you hate it when your water pipe gets dirty ash in it?? Zob Glass has the solution. This ash catcher from Zob Glass stands approx. 5 inches tall. It features a flat disc percolator that cools, and filters the smoke before it even gets to your pipe. The joint on the ash catcher is at a 90 degree angle. It fits an 18mm. glass joint, and takes a 14mm ground glass slide. Zob goes to great lengths to make sure each piece is one of a kind, so the label you get will more than likely be different than the one pictured. We have limited number of ash catchers available, so if you have a certain label color you're looking for we'll do our best to make that happen. Call or email prior to ordering to see what we have available. - Perc: Flat Disc Percolator - Height: 5.00 inches - Base Width: 2.25 inches - Glass Thickness: 5.00mm. - Slide: 14.00mm.
