Our newly designed advanced workbench caster lift system features thicker steel, stronger screws, and 6-holes on the plates, equipped with high-quality wheels and bearings. The wheels are made of durable solid steel and polyurethane, allowing smooth 360° movement. The wear-resistant polyurethane wheels are more suitable for heavy-duty workbenches, enduring the test of daily frequent use. We've also added rubber covers to the contact areas for a more comfortable user experience. Each lifting pedal is designed with raised textures, providing additional traction for a more stable stepping. The 4-polyurethane casters together can support a total weight capacity of 880 lbs. It's easy to operate, simply press down lightly on the pedal to raise your workbench from the ground. Once raised, you can move your workbench, table or machine as needed, then lift the pedal again to return to the original working height, securely placing the workbench, table, cabinet, stand or machine on the ground. Enhance your productivity by choosing the advanced workbench caster lift system, adding convenience and reliability to your workspace.
