The gridline to dome perc can be made with the 60 hole, 120 hole, or the 180 hole triangle.  I usually put the dome perc about 2 inches above the main perc.  The dome perc comes with either a spike as shown, or a small matching color ball (you can email me which you want or the default is a ball). These double perc tubes really function!  Full color accents on the mouthpiece, joint, bridge, base lip, and ring seal under the perc. 18mm hand made, hand ground female. Height ranges from 18 - 19" tall.  All tubes come with either a free clear 1hole slide or an AshMe mat that will be chosen for you unless you reach out and let me know. Custom slides are also available in the accessories section.
