Nolan's lightweight, strong and easy to apply model C Railcar blocks are made of tough carbon steel. The car blocks are designed using a rotating cam locking device for extra safety. The greater the force applied to the cam, the more tightly the car block grips the rail. The car block locks so tightly that they are used to prevent rail car movement on barges.
