Signode RCD-1431 Steel Strapping Sealer
The RCD-1431 is used with 1.25” high tensile steel strapping. It applies a double notch, up-cut reverse notch seal. This tool weighs 7 lb. Signode just released a high efficient battery sealer for steel strapping: Grip Pack 114.
This is a top of the line tool. If you want a less costly tool try the exact replica of the RCD called the SDN114.
