Max-BlastTMStemming Plugs are the most effective vinyl plug on the market. The patented "positive seal' accordion design forms a barrier that prevents the explosive gasses from passing up through the stemming material. When the stemming material is undisturbed by rapidly expanding gas it will bridge and lock up in the borehole.
Max-BlastTMPlugs employ a simple "Friction Fit" approach. They install in seconds. Simply push the plug into the borehole point down using a charging pole.
