This 300 lbs capacity model features hard rubber wheels, good for smooth surfaces. Impervious to oil, grease, and water. Extremely durable.

Overall height: 4"

BMI's tri-wheels are used in Hollywood, on Broadway, and in countless theatres across the country.

Note: These casters are designed for use on even surfaces like stage floors.  The 2" wheel diameter is not ideal for travel over raised thresholds, truck ramps, etc. A larger diameter. single-wheel caster would offer better leverage for traversing uneven surfaces or inclines.
