The Sap Sak is the most affordable gravity sap collection method we currently have available. The Sap Sak has been on the market for 20 years and has proven its performance time and again. The Sap Sak will work with 5/16" or 7/16" hookless aluminum spouts. The Sap Sak can not be used alone. It must be used with the Sap Sak Holder.
