An erector set is a construction kit of metal strips with holes, plates, nuts and bolts that you assemble with included tools into vehicles, machines and landmarks. Unlike brick sets, the parts are fastened mechanically, so each build is a small assembly project with real wrenches or screwdrivers.
The six sets below run from a 236 piece starter kit to a 1,203 part race car model. Counts and contents come from each product’s listing page. We have not used these sets ourselves. Educational and durability claims are the makers’ own.
