Pick up your Mini 4WD machine safely and smoothly using this unique piece of equipment. What's more, it requires no gluing or screws etc. to assemble! Made by simply folding and tucking in the 0.75mm polypropylene (PP) material. 3 raised ribs on the base of the entry chute help to slow down the machine before it is caught. The assembled catcher can be stored as is, in the lower section of the Portable Pit.
