This traditional Lamb tubing spout is designed for use with a 7/16" hole drilled into a maple tree.
The hole needs to be drilled 2 inches deep into the tree, and then the spout tapped lightly into the hole, using a hammer. When tapping the spout in, use wrist action only while swinging the hammer. Tap lightly until the hammer bounces back off the spout, and a "thud" sound will be heard.
***DO NOT OVERDRIVE THE SPOUT INTO THE TREE: you will risk splitting the tree.
The spout has a barbed fitting to connect to a 5/16" drop line tubing of the maple sap tubing system.
