The Pneumatic ST400 fencing stapler was built to solve the problem of using a hammer to drive staples into wooden posts.
It is compatible with 4mm diameter / 9 Gauge (40mm, 45mm or 50mm / 1 1/2", 1 3/4" and 2" long) staples. The pneumatic ST400 fencing stapler's aluminium alloy housing means that it is lightweight and corrosion resistant for extreme durability.
