This is a type of proppant sand delivery box used in  the hydraulic fracturing process. it is delivered to site via trailers, and then loaded onto a trailer that unloads and transfers the sand to the next machine in line, usually a blender, which then sends the sand down into the well.  Thi s is based on the Prop X brand and is a scale 8' square. Yes, I offer both versions of the trailers mentioned above. Questions? email modelmechanic@gmail.com
