The beveled edge of this gavel banger creates a better seal with bubble/ball style carb caps. The thicker 3mm wall is a good medium between the 2mm standard wall and the thick 4mm variants. It will heat up quicker than the 4mm and stay hot longer than the 2mm so if you are looking for something in that range this is the perfect banger for you. The thick 4mm bottom plate comes standard.This style is available only in 90 degree angle. This beveled banger comes in a custom Clear Encore box.
