This set of Ladders, Step Ladders and Scaffolds by Ngineering includes 10 50-foot lengths of industrial ladder in two groups of two different widths; various foldable step ladders; leaning ladders and three scaffold assemblies complete with side-rails. The scaffolds are of the type you would see being used by window washers or painters on buildings. The ladder rungs are etched to an extremely fine width giving them a very prototypical N-Scale appearance. Instructions in the Ladders, Step Ladders and Scaffolds set includes an explanation of how to use the supplied parts to make extension ladders. Etched-metal parts are unpainted.
