Material Handling Trolleys. The 300-4 is the workhorse of warehouse and factory trolleys worldwide. Its 10-inch diameter balances maneuverability with load stability. The R1 agricultural tread provides enough grip for concrete, tile, and asphalt without excessive rolling resistance.
Garden & Utility Carts. Popular with DIY enthusiasts and landscaping professionals. The Maxtop value-tier pricing makes it the most cost-effective option for consumer-grade wheelbarrows and garden carts sold through hardware retailers.
Construction Equipment. Used on light construction equipment, concrete mixers, and material carts. The ball bearing hub ensures smooth rolling under load. Flat-free construction means zero downtime from punctures on job sites littered with nails and debris.
OEM & Replacement. Standard 3.00-4 fitment makes it a direct replacement for worn-out wheels on most European and Asian trolley equipment. Common replacement for brands sold through Bauhaus, OBI, and Leroy Merlin.
