This set of 4 - 2 in. casters is designed for everyday use in home and office environments, fitting furniture, cabinets, bookshelves and light-duty service carts. Each caster supports up to 150 lbs. with a combined total load capacity of over 600 lbs. for the full set, supported by double ball bearings for consistent, reliable strength. The soft rubber tread delivers quiet, smooth rolling without jerky starts or distracting noise, while also protecting hardwood, tile and carpet floors from scuffs or damage. A dual locking brake system locks both the wheel and swivel mechanism at once to prevent unwanted movement, boosting safety and stability during use. The full package includes 4 casters, screws, washers and a screwdriver, and users should count all pieces before starting installation, reaching out for replacements if any parts are missing.
