Frequently Asked Questions
What is Duratek rubber? ›
Duratek is a premium rubber compound engineered for extended tread life compared to standard TPR. It resists flat-spotting and chunk-out under sustained heavy loads.
How is Duratek different from standard TPR? ›
Duratek uses a higher-grade rubber compound that lasts longer and resists wear patterns from stationary loading, making it better for shelving that sits in one place.
Are Duratek casters non-marking? ›
Yes. The Duratek compound is non-marking and floor-safe on all hard surfaces.
