The helmet adapter is one of the company’s top-of-the-line products. It is characterized by especially innovative features such as a lever and bending system, using torsion springs with a spin gauged to move the earplugs backwards. It also has a smaller amount of parts than its competitors, and uses simplified tooling. It can be adapted to any helmet brand. It is injected in ABS and receives a fiberglass load to cope with the wear and tear. With less movements and adjustments, users can remove and put the earplugs on intuitively, which contributes to improve their work conditions. The product was developed in Brazil with technical, functional and formal aspects that compete in equal conditions with imported products.
