together with paired serial numbers s. Anodizing after machining
creates a smoother surface for bearings to move against, decreasing
wear and lifetime lubrication delivers maintenance-free performance.
"Our unique manufacturing processes work together to achieve
this durability," Cronk said. "Proving our aluminum geared
continuous hinge will last for more than 60 years of heavy use gave
us the confidence to offer the industry's only Continuous Warranty.
