Erector Set
Erector Set is the trade name of a toy construction set that was wildly popular in the United States during much of the 20th century. Like Meccano, it consists of collections of small metal beams with regular holes for nuts, bolts, screws, and mechanical parts such as pulleys, gears, and small electric motors. Erector beams have flanges, which make them sturdier than those of Meccano.
The Erector Set was invented by A.C. Gilbert in 1911, and was manufactured by the A. C. Gilbert Company at the Erector Square factory in New Haven, Connecticut, from 1913 until its bankruptcy in 1967. Currently sold "Erector" sets are actually Meccano sets manufactured by Meccano S.N. of France, part of the Nikko Group of Japan.
