Designed to meet the durability, all-day comfort and safety requirements while working at heights on a construction site, the new Miller Revolution Construction Harnesses offer the same key features that have made the original Miller Revolution Harnesses the most comfortable and user-friendly products available. A construction site is a tough environment, however the design and materials used on these construction harnesses are up to the task. In fact, the harnesses use Type 10 webbing that is almost twice as strong as the standards require, and is certain to provide the longest service life possible.
