“Tool Source had the best price, in stock.”— Reviewer4266202009
Traditional manual caulking guns require trigger pressure to create push rod force. Most guns have a 4 or 5 to one ratio, 40 pounds on the handle produces 160 pounds of force. The MERITOOL gun takes one pound of trigger force and creates 180 pounds of force in the DS110 and almost 500 pounds in the DS130.
