Overview
The Arrow JT21CM is a staple gun, part of Arrow's long running JT21 model line, one of the more widely recognized light duty staple gun designs. It weighs 14.4 ounces, light enough for one handed use.
The listing title here reads simply 'General', which looks like a placeholder rather than a real product description, so the JT21 model number is the more reliable signal of what this tool actually is. The CM in the model likely denotes a specific finish or color variant, though that isn't confirmed in the available data.

Performance notes
At 14.4 ounces, this staple gun is light enough for extended one handed use on smaller jobs like upholstery, screening or insulation. As a manually squeezed tacker rather than a pneumatic tool, it trades raw driving power for portability and no need for an air compressor, which suits lighter materials better than dense hardwood or thick lumber.
