Key benefits Fast, consistent fastening for high-volume or precision work — reduces rework and speeds up assembly. Long magazine (140 staples) minimizes reloads and downtime on the job. Adjustable, reliable pneumatic operation delivers consistent drive power at typical job-site air pressures (4–7 bar / 60–100 psi), ensuring secure stapling in a variety of materials. Fine-crown, long-nose design improves access to narrow spaces and delivers a neat finish for trim, upholstery, and cabinetry. What this tool does and why you need it Delivers ga21 (0.90 x 0.70 mm) U-style staples with lengths from 6 mm to 16 mm, providing a balance of holding power and low material split for wood, fabric, and composite substrates. The 1/2" long nose pneumatic stapler / 1/2" fine crown pneumatic stapler configuration lets you work close to edges, inside corners, and tight cavities where standard staplers cannot reach. Operates on common workshop or job-site air pressure, making it compatible with most compressors that can supply 4–7 bar (60–100 psi). Key specifications Staple style: U style Staple length range: 6–16 mm Staple gauge and size: ga21, 0.90 x 0.70 mm Magazine capacity: 140 pieces Operating pressure: 4–7 bar / 60–100 psi Model form: 1/2" long nose pneumatic stapler / 1/2" fine crown pneumatic stapler Performance and compatibility Designed for consistent depth and secure seating at the specified air pressure range; avoid using compressors or hoses that cannot maintain 4–7 bar (60–100 psi). Holds 140 staples for extended run time between reloads, improving productivity on longer jobs. Fine crown and ga21 staples offer strong holding force while minimizing visible finish damage on delicate materials. Practical applications (use scenarios) Upholstery: Secure fabric to frames and attach webbing in couches and chairs where a long nose and fine crown create a clean, tight finish. Cabinetry and trim: Fasten narrow trim pieces and moldings in tight corners or tight clearances without crushing or splitting thin stock. Light assembly and packaging: Attach components, light substrates, or corrugated materials quickly with consistent staple placement and holding strength. Tips for effective use Set compressor and hose fittings to maintain 4–7 bar (60–100 psi) for best performance and to avoid misfires or overdriving staples. Use staples within the ga21, 0.90 x 0.70 mm specification and 6–16 mm length range to ensure reliable feeding and correct fastening performance. Check magazine capacity (140 pieces) before long runs to plan reloads and avoid interruptions. What makes this stapler stand out Combines a fine crown (1/2") profile with a long-nose design for precision access and a neat finish. Large magazine capacity and compatibility with standard air pressures make it well suited to both shop and on-site use. Exact staple specification (ga21, 0.90 x 0.70 mm, 6–16 mm lengths) ensures predictable, repeatable results across common light-to-medium fastening tasks.
