Amplify the functionality of your work and prep tables with the Pearington Work Table Caster Wheels. This heavy-duty set of 4 zinc-plated 4" x 4" ball bearing swivel caster wheels is made especially for stainless steel commercial kitchen prep tables, offering an easy way to transform your prep tables into a mobile work surface. Designed for optimal support and efficiency, the tube adapter caster supports up to 300 pounds per caster for a generous 1,200 pounds total, and each table leg caster has an integrated brake that can be locked down to keep the table securely in place when needed. Additionally, the stainless steel casters are non-marring and easily pivot on a full set of ball bearings to roll smoothly and quickly on almost any surface including tile, concrete, wood, and beyond. The wheels arrive fully assembled and easily slide into the 1.5" legs to make installation a breeze, and the included rubber compression fitting at the top allows you to tighten the top ring to achieve the perfect fit inside each table leg. Constructed from durable chemical-resistant thermoplastic polyurethane, these composite 4" work table stem casters withstand heavy-duty use in the kitchen or other commercial settings for years to come.
