Ackwheel Fixed Double Caster Wheel is a light-duty mobility component designed for unidirectional movement with enhanced stability. The "fixed" or "rigid" nature means it does not swivel, making it ideal for applications where straight-line travel is required. The "double wheel" or "twin wheel" design distributes the load over a wider surface area, offering better stability and smoother rolling compared to a single wheel, particularly on softer surfaces or carpets.
