These are custom type 304 stainless steel square u bolts we supplied to our customer at 73 pieces.  Since no outside plating or coating services were required these u bolts were completed within 1 week of confirmed order and were shipped with material certs per the customer's specification.  The inside width is 4" and the inside depth is at 9".  Two inches of coarse thread was incorporated at each leg.

Our relationships with factories all over the United States and abroad based on decades of custom hardware & fastener production history, in combination with the flexibility of blanket purchase arrangements, allows us to fully cater to the customer’s hardware specification and procurement requirements.
