PROTO OFFERS MORE THAN JUST TOOLS. WHAT WE OFFER OUR CUSTOMERS IS PEACE OF MIND

Three miles down in the earth at the bottom of a coal mine. An oil rig in the Indian Ocean. A battlefield in a war-torn country. These are places where keeping the work going is mission-critical because lives may be at stake. Our customers work tough industrial jobs in extreme environments and the impact of injury or work stoppage can be catastrophic and costly. That’s why they demand the most durable and safest tools in the world.

When they buy from PROTO® they aren’t just buying tools. What they are buying is confidence that our tools will help keep them working longer and safer. To ensure this, the PROTO® brand must always be unique in the marketplace, relevant to our customer’s work style, and authentic to our company’s values and heritage. Lastly, these objectives must be implemented consistently to build recognition and trust in the PROTO® brand.
