Also known as zero throw casters, the effort required to turn the casters and move the platform in the opposite direction is a fraction of that required with plain swivel casters. Made of steel plate, heavy duty ball bearings, and load rated casters, the tri-wheel caster will ease your scene shifts. Comes assembled.

This 300 lbs capacity model features neoprene wheels, excellent on all surfaces. Superb rejection of floor debris, very quiet operation. Rounded tread allows for effortless swiveling.

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.
