Smooth, silent, and sturdy low profile caster wheels designed for heavy loads while keeping a low clearance. Key benefits Low profile design lets you move heavy items without raising the item height. Smooth and quiet rolling on a variety of floor surfaces for less noise and reduced floor wear. Durable construction for reliable load bearing and long service life. Materials and construction Wheel material: thermoplastic rubber (TPE) for a soft, non marking surface that resists oils and common chemicals. Metal parts: cold rolled steel mounting plate with reinforcement at the bend to reduce deformation under load. Built in ball bearing provides 360 degree rotation for flexible, stable movement. Brake mechanism lets you stop the wheel and lock direction as needed. Installation and compatibility U shaped mounting plate design. Please confirm the size of the U shaped bracket before ordering to ensure proper fit. Screws are included for quick installation; most installations take only a few minutes. If the casters do not fit, contact the seller before returning the product; describe the problem and a preferred solution and a satisfactory resolution will be offered. Performance and floor suitability Non marking TPE wheel surface performs well on marble, laminate, hardwood, and many carpeted floors without scratching. Quiet mobility combined with strong load bearing makes these casters suitable for frequent use. Typical applications Workshop carts, tool cabinets, and equipment stands that require heavy load support with minimal added height. Office furniture, storage racks, and display units moved across smooth floors without leaving marks. Kitchen islands, mobile shelving, and plant stands that need quiet, stable rolling and a low profile. What to check before ordering Confirm U shaped bracket size and mounting dimensions to ensure compatibility. Verify floor type and intended load to confirm this caster meets your application needs.
