ST400i Cordless Fence Post Stapler


The ST400i is the worlds first 4mm diameter / 9 Gauge cordless fencing stapler that makes fencing faster, easier and more safer for the fencer/fencing contractor.

The ST400i Cordless Fencing Stapler is just as powerful as our popular Pneumatic ST400 fencing stapler but is not reliant on compressors and hoses. This fencing stapler is revolutionizing stapling in the fencing industry. It is safe and allows you to fire staples with one hand, allowing you to keep your second hand out of harms way.

The ST400i has outstanding power allowing you to fire up to 750 staples per fuel cell (depending on temperature) and in conjunction with the 3.7V Li-ion battery, you can fire 3000 staples per charge per battery. This tool is also compatible with the Power Staple Insulator Guide Attachment allowing you to easily erect an electric fence using the PEL/Speedrite/Stafix Wood Post Claw Insulator.
