The custom-designed R-Trac Wide wheels feature low profile no-flat tires, lightweight but strong polymer hubs, low rolling resistance, pneumatic-like cushioning, vastly wider load dispersion over soft terrain, and a stunning racing-style look. 6″ x 3″ brake casters are 50% wider than typical casters and can glide over soft terrain.

The RCSTR6X3 is a replacement caster for the R16RT and can be purchased as an upgrade caster for the R14RT.

Sold as a set of 2 casters
