Stopper for Heavy Rods 25mm Lowrider CNC

Well this was build as I bought heavy Linear rails. No matter how tight u seem to have lock it, it will slide off... Thus it is best to have a secondary lock so that it will stop it from going off. It will be painful if it slides off and hits anyone's toe. These linear rod are heavy if thick and dangerous if thin as it could cut off the skin. Safety First
