At Nicewind, we can design the cart just the way you need it. We can make it with higher or MUCH higher sides, with the base tailored to the perimeter you specify. We can also make them with a side or rear gate and choose from a range of colors. Depending on what you want to transport and the surface on which the load will be moved, we can fit one wheel or another, and they are easily interchangeable. We have the material and the technique to do it. We just need your requirements and a short period of time to study them and adapt the assembly to your requirements. We can transform our Gerri to whatever you need. Contact us or our sales representatives for more information. Thank you very much.
