A333 is made with a specially machined feed wheel and gripper,which is suitable for high tensile steel strapping bands. Also available for the torque wrench tensioning system (TW model).It is normally used for strap flat packages (i.e. pallets, bales, crates, cases, various packages). General specification and high tensile strength of the steel strip can be used. Because it is free of button connection, do not need to use the other steel buckle. The average tensile strength of the deduction is about 80% of the tensile strength of the steel strip, which is very reliable and can save about 10% of the total package cost.
