SDI Long-Arm Heavy-Duty Stapler, 2–240 Sheet Capacity – for Office & School

This stapler has a 240-sheet capacity, making it ideal for heavy-duty office or school projects that involve large documents.

The extended arm provides greater reach, enabling you to staple across wider paper sizes or thicker bundles in a single staple action, which speeds up batch binding and reduces handling time.

Key specs include a 240-sheet capacity, a long-arm design for extended reach, heavy-duty construction for consistent performance, and versatile use for industrial or office-level stapling needs.

Use cases include binding large reports and manuals, assembling school or office project binders, compiling thick presentations, and any task that requires stapling many pages at once.

To load staples, place the stapler on a flat, stable surface, open the rear loading tray, insert the appropriate large-capacity staples, close the tray, and then squeeze the handle to staple. If the model supports a depth adjustment, set it before stapling and reload staples when the supply runs low.

Yes. Use the stapler on a flat, stable surface, keep fingers away from the anvil and moving parts, avoid forcing staples, and store it out of reach of children when not in use. Regularly clean dust and debris from the mechanism to prevent jams.

Wipe the exterior with a soft cloth to remove dust. Periodically apply a light machine oil to the moving parts if you notice stiffness, and keep the loading area free of obstructions to prevent jams. Store in a dry environment.

If you frequently bind large documents or need to reduce reloading during busy periods, the 240-sheet capacity and durable construction offer efficiency and reliability that can justify the investment, especially for office or school use.
