What do we do?


Started in 1971 in Birmingham, AL, Utility Tool Company is a small, privately owned firm.  We design, manufacture, and sell patented electronic equipment under the trade name Pipehorn for locating and troubleshooting underground utilities from above ground.  Utility companies, contractors, maintenance crews, and professional locators, throughout the U.S. use Pipehorn equipment to increase productivity and prevent damage.  We utilize our expertise in electromagnetics and electronics in conjunction with our knowledge of underground utility location and construction to develop and sell equipment to our target markets.

A little history on Pipehorn...

The original Pipehorn was invented in 1968 & patented by Tom Humphreys, an Alagasco engineer, to solve the problem of locating cast iron pipe.  He truly built a "better mousetrap" for locating.  Utility Tool Company purchased the rights to manufacture and sale.  After his retirement, he assisted us with the development of other products.

In 1972, we moved to our current location just east of Birmingham in Irondale, AL. We completed renovation of our facility in 1998, effectively tripling the size of our plant.  Our product line has grown from the Classic Model 100, to include the following items:

800 Series Pipe and Cable Locators

MD450 Maghorn Magnetic Locator

PA400 Valve Box & Manhole Cover Locator Attachment

Our Business Philosophy

Technology alone does not drive our product development.  Rather, we seek to understand users' problems, then provide solutions.  Each of our products have grown out of users' needs.

Building quality products which are rugged and simple to use is the core element of our approach to overall product design.

We invest in user education to ensure that our customers receive maximum value from their Pipehorn equipment.

Through our products and training, we strive to save our customers time and money.  Well-satisfied users have been the key to our success for over 45 years, and we strive each day to keep it that way.
