The 7oz. Epoxy Gun is constructed from heavy duty steel and is designed for larger volume shops. The 7oz. gun can be used to dispense 1:1 or 2:1 ratio, 200ml epoxy cartridges such as The GolfWorks Tour Set (VB1027) and Maximum Strength Quick Set (VB1026) epoxies. The optional Static Mixing Tubes (VB1029) can also be used to dispense thoroughly mixed epoxy directly from the gun.
