Our interlocks control access into potentially hazardous areas, ensuring the area is safe before the employee can enter and keeping the employee safe while a task such as essential maintenance is being carried out.
We believe every employee working in a potentially dangerous environment around the world deserves the best possible protection, so we manufacture solutions to order Australia, UK, USA and China along with sales offices in the Netherlands and India. Our large global network of trusted safety partners ensures our customers and their individual needs are fully supported around the world.
