ABSTRACT:
A pocket, lid and shield for casting a pulling iron in a concrete structure are described. The pocket includes a slot reinforced with stiffening members for receiving the pulling iron. The pocket also includes a frangible support post for supporting the pulling iron when it is received in the pocket. Also described are embodiments of a shield, which include clipping members adapted to engage the stiffening members, for covering the slot, and a lid having a lip for engaging a peripheral groove in the pocket. Methods of over-molding a pulling iron cable are also described. According to the methods, a temporary seal, which can be used in over-molding a subsequent pulling iron cable, can be formed simultaneously with each over-molded product. During molding, the cable can be held in the center of a channel in the mold tool using a retractable magnetic pin.
