Move your heaviest PA gear with confidence using these heavy-duty 4-inch swivel casters. Built for musicians, DJs, and venues who need to transport speaker cabinets, rack cases, and flight cases without straining their backs or requiring multiple people for setup.

Each caster handles up to 500 pounds, making them suitable for fully loaded rack cases, large speaker cabinets, and multi-piece PA systems. The non-skid rubber wheels protect venue floors while providing smooth rolling across different surfaces, from carpet to concrete.

The 4-inch wheel diameter with steel frame construction delivers the durability needed for regular transport and setup cycles. At 5 inches from mounting plate to floor, these casters provide enough clearance for most gear without making your cabinets too tall for transport. The swivel design allows 360-degree rotation for tight maneuvering in cramped backstage areas or narrow venue entrances.

Perfect for mobile DJs moving between wedding venues, bands with regular gigs, churches updating their sound system mobility, and rental companies maintaining flight case fleets. Also ideal for permanently installed systems that need occasional repositioning for different event configurations.

Each caster mounts with standard bolt holes to existing threaded inserts or mounting plates. The four-pack provides complete mobility for one cabinet or case. Seismic Audio backs these casters with reliable construction that handles the demands of professional audio transport, with fast shipping to keep your mobile rig moving.

Frequently Asked Questions

What weight can these casters handle for a full speaker cabinet?

Each caster supports 500 pounds, so a four-caster setup can handle up to 2,000 pounds total. This capacity works for most powered PA speakers, subwoofers, and fully loaded 12-space rack cases. Always distribute weight evenly across all four casters for maximum stability and longevity.

Will these casters fit my existing speaker cabinet or rack case?

These casters mount to standard threaded inserts or mounting plates found on most professional audio gear. Check your cabinet's corner mounting points - most use either M8 or 1/4-20 bolts. The 5-inch total height adds minimal clearance while providing smooth rolling capability.

Do I need locking casters or are non-locking fine for live sound?

Non-locking casters work well for transport and repositioning, but consider your venue setup. If you're placing speakers on a stage where they won't be moved during the show, non-locking is fine. For setups where equipment might shift during performance, locking casters provide extra security.

How do these casters perform on different venue floor types?

The non-skid rubber wheels roll smoothly on concrete, wood, and low-pile carpet while protecting floor surfaces from scratches. They handle typical venue conditions including slight inclines and door thresholds. Avoid using on gravel or rough outdoor surfaces where debris could damage the wheels.

Can these casters support a loaded subwoofer during transport?

Yes, these casters can handle most subwoofers including loaded models. A typical 18-inch powered subwoofer weighs 80-120 pounds, well within the 2,000-pound total capacity of four casters. The steel frame construction and rubber wheels provide stable transport even for bass-heavy cabinets.
