These steel caster wheels simplify transport for PA speakers, subs, racks, and more. Zinc-plated, 3" swiveling hardware offers smooth mobility with a locking mechanism that resists movement from vibration. A 350 lb load rating supports heavy gear stacks, while double ball race construction adds stability. The compact plate mounts to cases and cabinets with standard hardware, speeding setup and teardown for touring rigs or weekly gigs. Ideal for line arrays, 18" subs, and AV carts, these casters bring reliable movement to demanding schedules and tight load-in windows.
