For light duty projects on the job, Arrow’s Professional Light Duty Staple Gun is a great addition to any toolbox or workshop. Of course, the term 'light duty' refers to the scale of the projects, not the strength of the staple gun- which is built with the same quality as all Arrow tools. With a sturdy all-steel body and chrome finish, the JT21CM is ready to get the job done. Compact and lightweight, this tool works with all sizes of JT21 Staples. Perfect for upholstery, screen repair, and professional light duty projects.
