Casters — Mercury (4 Brakes) (Set of 4)

The Master Manufacturing Mercury Caster Series (D472-1/2) is a premium 2-1/2″ tapered wheel caster designed for smooth mobility on carpeted or hard floor surfaces. These heavy-duty casters are trusted in offices, schools, healthcare facilities, and industrial environments for their durability and ergonomic rolling action.

Featuring a slightly larger wheel diameter than standard 2″ casters, Mercury Casters reduce rolling resistance and improve movement over thicker carpet or uneven flooring. Available with hard wheels for carpet or soft wheels for chair mats and hard floors, these replacement casters are compatible with most office chairs using standard grip ring or threaded stems.

• Optional step-on brake models are available for extra safety and stability.
• Ideal for upgrading broken or low-quality chair wheels
• Compatible with most office and task chairs
• Available in 4- or 5-piece sets
