The Monkey Pipe was the first in our line. Made with stainless steel nuts and screws and with a stainless steel lining in the bottom, the Monkey Pipe is a breeze to clean. Two ventilation ports through the center of anodized aluminum keep the unit cool. The Monkey Pipe measures approx. 1 6/8" in length 11/16" in width and 15/16" in height when closed. It uses a 5/8" screen.
