Why Choose This Tool?
-
Engineered for demanding fastening tasks where strong hold and high productivity matter.
-
The medium-crown heavy-wire design offers a broad footprint for tougher materials without the bulk of ultra-wide crowns.
-
Durable construction, fast reload and jam resistance make it suitable for continuous use in industrial environments.
Things to Know Before Buying
-
Requires a clean, regulated compressed-air supply capable of 70-120 psi; consistent pressure is key to proper staple penetration and clinch.
-
Ensure your staple inventory matches the specification: 16/17 ga heavy-wire, 1″-2″ leg length, 7/16″ crown width.
-
At ~5.1 lbs, it's manageable but still a full-power production tool—ergonomics, operator rotation or breaks should be considered for extensive use.
-
Best suited for mid-to-heavy duty tasks; if your materials are very thin or you need lighter/less bulk tools, a smaller crown or manual model may be more efficient.
