Hamilton's new Ergo-Tech, formerly Polylast™, is one of Hamilton's best rolling wheels. As the name implies, the Ergo-Tech is an ergonomist favorite and designed to minimize push/pull forces and reduce work-related injuries. The unique half-round or donut-type tread is combined with maintenance-free precision ball bearings to provide effortless rolling.
Engineers specified a high energy, softer 87A durometer polyurethane to ensure greater traction, repel foreign objects & debris, and run quieter than most other urethanes.
Ergo-Tech was designed and built from the ground up to be Hamilton's best choice for ergonomics. If ok with slightly higher push/pull and require more durability, check out our Ergo-Glide™
