The DIVISIONAL Composite Caulking Gun is a high-strength caulking gun for multipurpose use. Thanks to its high pushing speed, 10 oz/300 ml caulking tubes can be easily handled. The reinforced monoblock composite body reduces weight while increasing strength. Our efforts to produce the most durable and long-lasting body for the caulking gun have come to an end. As a result of these studies, we realized that if the body has a monoblock structure, it will have a very strong structure. However, we understood the importance of hardening material in body production. When the body reached the sufficient and desired hardness, we turned to the renewal of the spring and propulsion mechanism. With the work we did on the spring mechanism and the drive mechanism, we managed to produce this strong, durable and long-lasting caulking gun that we offer for sale. We realized that metal caulking guns tire people because they are both cold and heavy, so we designed an extremely strong and lightweight caulking gun made of composite material. The 1/4 inch thick body construction gives a solid feel when using the caulking gun. We are sure you will be satisfied with this very robust and long lasting caulking gun.
