Our Story

Harold Allen Company was founded in Idaho by Harold Allen, a fire-sprinkler professional who saw a need for better tools — tools that made the job faster, safer, and more precise.

Today, the company is run by family who continue to manufacture every tool with the same hands-on approach, personal accountability, and obsession with doing things the right way.
