A Little History

Our Products

In 1993 the Dollahan family started building Hay and Grain feeders. At that time, they were very into horses. The family spent every weekend on the road running and gaming. As the years went by, they sold Hay and Grain feeders in several retail locations across the United States. In 2011, Russell and Mollie Dollahan took over the family business. They kept things the same for while, but instead of spending their time with horses, their kids wanted to show pigs. That's how the 4D stock pens were born. 

As the years went by, time wasn't available to keep all product lines alive. So now 4D is fully focused on show stock penning systems. Find all our products below, but just because talking about it makes us sentimental, we included a pretty old photo of our kids with our original product because we believe that your roots matter.
