5/16 Soule Sap Tap
Soule 5/16" Hookless Aluminum Spout has been an industry standard for many years. This cast aluminum spout works well with the Sap Sak holders.
Use with 5/16' Drill Bit
Also works well with Buckets.
The left end (in the picture) goes in the tree and a hole in the side(near the top) of the bucket is slid over the notch (which is facing skyward). This way, a lid can be placed on top of the bucket preventing snow/rain/bugs from getting into the sap. Because the bucket is resting on the notch of the spile, it wont slide off.
