摘要： A cast silo lug combining compact structure with superior strength has a body portion with two holes therein, a curved lip section associated with each hole and a mounting section for positioning the lug against the wall of a silo. The holes are positioned at opposite ends of the body portion. One lip section extends outward from the body portion and around the part of the circumference of a hole facing the end of said body portion. The second lip section extends in the same manner outward from and around the other hole but on the opposite side of the body portion. The threaded end portions of silo encircling rods are passed through the holes in opposing directions, the lip sections associated with each hole serving to support the rod passing through the hole. On the side of each hole opposite the lip section, a bearing surface is provided for the retaining nut used to secure and tighten the encircling rods to the wall of the silo.
