The ST400i Cordless Fence Staple Gun is as powerful as the original STOCKade Pneumatic ST400 fence stapler but does not rely on compressors and hoses. After listening to our customers, we have engineered this tool to help you be even more efficient during the day. This cordless fence stapler will revolutionize stapling in the Ranch world and fencing industry.
 
The ST400i Cordless Fence Stapler impulse technology has outstanding power, allowing you to fire up to 750 staples per fuel cell. In conjunction with the 3.7V Li-ion battery, you can fire up to 3000 staples per charge per battery. The ST400i Cordless Fence Stapler kit also comes with two batteries. A charger included has 110V and 12V cables provided for versatility in charging, so you will never run out of power.
 
The ST400i has a temperature sensor built into the handle that measures ambient air temperature, and the tool adjusts its fuel requirements based on that temperature. So, at 5C, the fuel canister is rated at 500 shots. The warmer the temperature, the less fuel is needed; however, as the temperature becomes colder, the fuel becomes less volatile. More fuel is required, so save some extra fuel cells built up from warmer weather operations. Excess fuel canisters and staples can be bought here at Prairie Fence if you are running low on fuel or staples.
 
Like any combustion engine, the fuel does the heavy work, with the battery providing power to run the electronics, fuel dosage, fan, and, of course, the spark to ignite the fuel. The explosion and gas expansion drive the internal piston down, which is attached to the driver; the driver then pushes the staple into the wooden post. The tool will always fire at the same force. Your depth adjustment is controlled by the tooltip, which, moved all the way out, will keep the staple 0.7 inches out; adjust the tip in, and the staple should drive hard to post, with adjustment in between and mm increments, so you can set that perfect staple depth you desire every time.
 
The ST400i requires an internal tool cleaning at 10,000 shots and a complete service every 30,000 shots at a STOCKade service center. This cordless fence stapler is compatible with the power stapler insulation guide attachment, allowing you to quickly erect an electric fence using the extreme power staple wood post claw insulation (sold separately).
