Benefits

Choose the right stem caster to match your cart’s load and floor environment. The polyurethane and polymer-housing options deliver the highest load capacity (up to 1200 lb per cart) for the heaviest Metro setups, ensuring stable, controlled movement of large inventories. Rubber variants offer alternatives for smoother rolling and floor interaction in settings where softer contact with the floor is preferred.

With four material choices, you can optimize for durability, maintenance, and floor compatibility without compromising mobility. The ability to buy casters individually provides flexibility to replace only what’s worn or damaged, keeping your Metro Super Erecta system ready for high-demand use.

Ideal for industrial kitchens, warehouses, medical supply rooms, and other busy environments where reliable, heavy-duty cart mobility is essential. If you’re upgrading an existing Metro setup, these stem casters integrate seamlessly with your existing frames and shelving.
