Aviation Chock Trolley
Avoid tripping hazards by keeping wheel chocks, safety cones and other small GSE tidy. Easy to move around by hand, and weather-resistant. One person can quickly move around the aircraft and place or remove chocks and cones, in the same amount of time it would take four to do. Made from high-grade welded aluminum, with foot-operated floor locks.
