Mobile DJs, touring musicians, and venue sound engineers need equipment that moves as fast as they do. The SARHW50 four-pack of 2-inch swivel casters transforms heavy PA speakers, subwoofers, and rack cases into easily maneuverable gear that one person can transport.

Each caster handles up to 100 pounds, giving you 400 pounds of total capacity per set — enough for dual 18-inch subwoofers or loaded rack cases. The 2-inch non-skid rubber wheels roll smoothly across stages, concrete floors, and outdoor surfaces without marking or slipping.

The chrome-finished steel construction stands up to regular transport, while the 2.5-inch height from mounting plate to floor provides adequate clearance. Each mounting plate measures 2 5/8" x 1 7/8" with 0.20" mounting holes that fit standard cabinet hardware. The non-locking swivel design allows 360-degree rotation for tight maneuvering in cramped backstage areas or storage rooms.

Perfect for mobile DJs moving between wedding venues, churches rotating heavy subwoofers for different services, or bands loading gear after late-night shows. Transform your heaviest cabinets into gear that rolls instead of requiring two-person lifts.

Installation requires basic wood screws (not included) and takes minutes per cabinet. Each set includes four matching casters with all necessary hardware except mounting screws. Backed by Seismic Audio's standard warranty with fast shipping to get your gear mobile.

Frequently Asked Questions

Will these casters fit my speaker cabinets?

The SARHW50 casters fit any cabinet with a flat mounting surface. The mounting plate measures 2 5/8" x 1 7/8" with four 0.20" holes that accommodate standard wood screws. Most PA speakers, subwoofers, and rack cases have sufficient bottom clearance, but measure your gear's recessed areas before ordering to ensure the 2.5" total height works with your setup.

Can these casters handle my dual 18-inch subwoofers?

Yes, with a 400-pound total capacity per set, these casters easily support most dual-driver subwoofers and loaded cabinets. Each individual caster handles 100 pounds, so even if weight distribution isn't perfectly even, you have plenty of safety margin. The non-skid rubber wheels provide stability during transport across various floor surfaces.

Do I need locking casters instead of these non-locking ones?

Non-locking casters work best for gear that needs frequent repositioning like DJ speakers or monitor wedges. Choose locking casters only if your cabinets will stay in one position for extended periods, such as permanently installed church sound systems. For mobile applications, non-locking casters are actually preferable since you can quickly adjust positioning without bending down to release locks.

What size screws do I need to mount these casters?

You'll need four wood screws per caster that fit the 0.20" mounting holes — typically #8 or #10 screws work well. Screw length depends on your cabinet's bottom thickness; plan for at least 1 inch of penetration into solid wood. The casters include mounting hardware except for the actual screws, since cabinet materials vary.

Will these wheels mark my floors or stages?

The non-skid rubber wheels are designed to protect floor surfaces while providing traction. They won't leave black marks like harder wheels might, making them suitable for churches, wedding venues, and other locations where floor protection matters. The rubber compound grips without gouging hardwood, tile, or carpeted surfaces.
