Every great invention begins with a problem worth solving. For us, that moment came in 2006. A new apprentice suffered a serious cut to his thumb while manually twisting ceiling hanger wire—a task performed thousands of times every day across the industry. It was a reminder that something considered "just part of the job" didn't have to be.
Determined to make construction work safer and more efficient, a father and son teamed up in a small garage in Milton, Ontario with one simple goal: create a better way.
After countless prototypes, testing, and refinement, the Serpent Wrench was born.
Designed to safely twist ceiling hanger wire to manufacturer specifications, the Serpent Wrench eliminates strain, inconsistency and injury risks associated with twisting wire by hand.
More than just another tool, it became the first—and remains the only—tool of its kind specifically engineered to produce consistent, code-compliant twists while helping prevent workplace injuries and installation errors.
What started as a solution for one injured worker has since become a trusted tool on construction sites across Canada and the United States.
Today, contractors, apprentices, foremen, and seasoned tradespeople use the Serpent Wrench to improve installation quality, reduce fatigue, increase productivity, and help workers return home safely at the end of every day.
Available in both 12-gauge and 9-gauge models, the Serpent Wrench is built to handle the most common ceiling hanger wire applications with stealth, consistency, and confidence.
The Serpent Wrench is proudly distributed across Canada through Wallboard Trim & Tool and is available online throughout the United States with flat-rate shipping.
