ND Tools takes pride in developing and distributing innovative new tools and materials for commercial construction with a focus on sustainable products. ND Tools is a family owned company,our new direction in tool development and distribution is reinforced by a long history in the commercial wall and ceiling industry both in New York and Montreal. I'd like to introduce everyone to a highly efficient and cost-effective alternative to paper or plastic caulking tubes, I call it the GPack, short for Green Pack. The GPack is an aluminum foil, tube-shaped, collapsible sealant cartridge often referred to as a sausage pack or a chub. Cheaper to make and more efficient for shipping, making the switch to GPacks can reduce cartridge waste by 90%! GPacks can be used in universal, Greater Caulk Guns; a GC-Gun. Light weight and rugged aluminum construction, GC-Gun's are designed for use with 10oz standard tubes, and 10oz to 34oz G-packs (sausage / foil packs). Long Reach GC-Guns can reach 10-13ft.
