The Arrow JT-21CM (often referred to as the "Junior" model) is a lightweight, compact staple gun designed for lighter-duty tasks.

• Design: It features an all-chrome finish with a compact, easy-to-use steel housing that is smaller and lighter than the heavy-duty T50, making it ideal for tasks where less physical strength is required.

• Applications: It is perfect for lighter jobs like craft projects, decorating, shelf lining, and small upholstery repairs.

• Ease of Use: Because it is designed with a simpler spring mechanism than the professional heavy-duty models, it is very user-friendly for homeowners and casual users.

• Staple Compatibility: It uses JT21 series staples, which are smaller and thinner than the heavy-duty T50 staples, tailored for lighter-gauge materials.
