This is a tough post to write. Stock-Ade staplers are by far the best in the fence business and built for every day use, are rugged and dependable and will last a lifetime if cared for properly. They use staples made specifically for their staple guns by Stock-Ade.
So, what to do when a cheaper copycat comes along? I don't want to burst people's bubbles by telling them that their imitation fence stapler probably won't be functional next year, but I've had fencers tell me their crews don't care for the tools and that even if they did get a ST400, they believed it would be ruined in a year anyway. So they bought a Chinese made imitation. Also, there are the small scale farmers who just want to fence an acre or two and have no need for an industrial tool. They just want the Harbor Freight equivalent.
All that being said, the Freeman staple gun was designed to use Stock-Ade staples and I do get orders from those folks and we are happy to oblige. We are also happy to let them (and you) know that if for any reason the Freeman is not performing the way you need it to, we will be here for you. In the mean time, we can supply you will all the staples you need.
