Double HH 50th Anniversary Open House
In 1973, Double HH Manufacturing in Rock Valley, Iowa, became the first to manufacture a heavy duty hitchpin with a red plastisol coated head and wide grip handle. Five decades later, we’re still producing the same high-quality hitchpins and agricultural equipment components you rely on today.
Come celebrate 50 years of pulling together since 1973!
Enjoy refreshments and tours of the Double HH plant, including our 35,000 square foot expansion!
Additional parking at Rock Industries on Hwy. 18, with transportation available to the Double HH Plant
