Our O Scale Cellar Door makes a great addition to any building. This door works with all buildings by Lionel, MTH and more. This detail part is sold as unpainted resin and was built to photographs and measurements of a real cellar door on the back on an older home. The photos show a painted version to give you an idea of how yours can be painted. Your casting comes in light gray resin, which means the cement sides don't need to be painted. As are all of our products, this cellar door is Made In America.
