3" Diameter, Shelving Wheel Compatible with Seville Classics Heavy Duty Stem Threader Swivel Locking Casters Set for Office, Kitchen, Garage, Warehouse, 4 Wheels

Upgrade your shelving units, storage racks, or mobile carts with this set of 4 heavy-duty swivel casters, designed for smooth-rolling stability and long-lasting durability. The 3" polyurethane (PU) wheels paired with reinforced steel hardware provide quiet operation and excellent load-bearing capacity, making them ideal for demanding environments like garages, warehouses, kitchens, and offices. Two of the four casters feature a convenient locking mechanism to keep your shelves securely in place when needed, while the swivel design allows for effortless 360° maneuverability. These casters are exclusively compatible with 1" diameter poles (not for 0.75" poles, carts, or worktables)—always verify your shelving specifications before purchase. Installation is a breeze thanks to the pre-threaded stems (1" length, 0.33" diameter), which screw directly into compatible poles without requiring extra tools. Whether you're replacing worn-out wheels or adding mobility to stationary racks, this versatile set ensures reliable performance for both indoor and outdoor use. Organize tools, workshop supplies, pantry items, or office equipment with enhanced control and stability!
