As the world gets away from single-use plastic tubes of caulking and moves toward Mylar sausage pack there comes a need for quality sausage guns in all sizes. We have offered 600ml/20oz sausage guns for quite a while and now we are introducing this 10.5oz - 13oz ETS4000 to fill the small sausage need. Same drive system, raw materials and features found in the ETS6000, just in a smaller package. Pick one up, use sausage packs instead of those wasteful tubes and we can all do our part to keep the landfills under control.
