This set of three heavy-duty adapter wheels is designed for use with compatible Matthews Combo stands, allowing a stand to convert to a mobile platform. The wheels provide smooth mobility, secure locking, and rugged construction—ideal for studio floors, location setups or rental gear that needs to move reliably. Key Features: Three-Wheel Kit for Mobility Conversion: Includes three locking caster wheels allowing a compatible stand to roll smoothly and be moved easily without removing the base. Spring-Steel Retainer for Secure Fit: Uses a spring-steel retainer system that clamps onto the stand leg without requiring drilling or permanent modifications. Locking Casters: Each wheel includes a brake mechanism that locks both wheel rotation and swivel direction, enabling secure stand placement when locked out. Heavy-Duty 4-Inch Wheels: Large diameter wheels provide better movement over studio floors or set surfaces and help protect gear from bumps or uneven floors. Steel Components for Durability: Wheels and hardware are made from steel rather than plastic, providing long-term reliability under production use.
