With a reduced drilling diameter of ¼''. it will minimize the zones affected by the tapholes. Offered in blue, black and now white. The compartmentalization zone is the area of dead wood caused by a taphole. The diameter and depth of the hole have a great influence on the extent of this area. Recent studies have demonstrated that by switching from a 19/64'' to a 1/4'' spout, the compartmentalization area decreases two to three times. If the growth sustainability of your forest is a priority, the ¼ spouts from the 708 Series is the wise choice.
