This combination tensioner, sealer, cutter comes out of Chicago area machine shop(s), that makes or made parts for Signode. It works with 1 1/4" steel strapping. We haven't tested every part, but it looks like the parts are interchangeable with the Signode PRHR-114 tool.
Allstrap Opinion: This combo bander is a solid tool. This tool is top quality, and at a fraction of the Signode PRHR-114 price. But, many pneumatic tools are switching to battery powered (click to link). We like this tool for a steel strapping pusher combo!
