Compare Duramaster Rod Cylinders vs Our Competitors
Duramaster’s NFPA-interchangeable tie rod cylinders, for example, are built with an eye to quality that is reflected in a careful manufacturing process and top-quality components from the inside to the outside—brass bushings, for example. Bucking the trend to cut corners, Duramaster continues to look for opportunities to upgrade these components over time.
