This set of 4 3in. caster wheels is designed to protect all types of hard floor surfaces, including hardwood, laminate, tile and slate. Made with thick polyurethane wrapped around an acrylic center, these wheels roll smoothly and silently without leaving scuffs, scratches or residue. Each caster supports up to 200 lbs., for a total 800 lbs. capacity for the full set, with a 3 in. wheel diameter, 2.36 x 2.36 in. top plate and 3.8 in. mounting height for versatile fitting. The 360° swivel design allows easy maneuvering of light furniture or display pieces, while integrated brakes let you securely lock wheels in place when needed. Suitable for wooden crates, shopping carts, dollies, workbenches, furniture parts and various equipment, these casters work for both home DIY and professional projects. If rotating noise occurs after long-term use, adding a small amount of lubricant to rotating parts will fix the issue without affecting performance.
