The making, shaping, and treating of steel for the manufacturing of the National Foundry electric eye is poured in-house to meet U. S. 1040 standards. Our Spectrolab facilities verify that these standards and codes are met. The eyes can be obtained for the application required for either 1, 2, or 3 strands as specified by the user. The threads on the eye vary as to the size of rod used. These threads are made according to National Course specifications. The eyes are coated with electric orange epoxy coating for maximum weather protection. They are also protected with a padded bag to prevent scuffing during shipping and delivery.
anchor rod has the chemical analysis: U.S. ASTM A36 and A52950 certified steels. The rods vary in size and length according to users needs. One end of the rod is either threaded for the screw-on eye or welded for the weld-on eye according to clients required specifications. The opposite end of the rod is threaded to National Course specifications. The anchor rod between the threads is covered mastic asphalt, then contained within a plastic rod sleeve for cathodic protection against electrolysis, rust, and corrosion deterioration. It then slips through the guide that is welded on to the National Foundry concave dish anchor plate and plastic washer. Then it is threaded into the coupling nut that holds the unit in place.
