Welcome to National Foundry

National Foundry and Manufacturing was established in Crane, Texas in 1974. We have been the world leader in oilfield, utility and electrical anchoring systems ever since. With oilfield applications, such as the Dragonback (3-wing expanding bottom anchor) and the Grip-Jaw (4-wing expanding bottom anchor), we are the dominating competitor in the oilfield anchor business. As these were the original anchor bottoms produced, they are time tested and proven reliable. In 1992, National Foundry expanded its product line to include service to the electrical/utility market, by producing one of the first cathodically protected anchors for electrical transmission, distribution, and use. With the recent explosion of the alternatve fuel market, National Foundry is developing applications specifically designed to take anchoring systems into the 21st century.


National Foundry remains committed to quality by producing only the best products. We continue to use only U.S. made steel, meeting strict steel requirements and standards. Our products are time-tested, and our commitment to quality enables us to better guarantee our products. We have a no-fail policy which is upheld in our electrical product line. Since its conception, we have had zero electrical anchor failures to date. National Foundry has taken the 8-way expanding-type anchor and adapted it to our cathodic rod. This conversion includes installing a rod guide, recoating the entire anchor bottom, and utilizing an insulating washer, thus ensuring better cathodic protection.

*Contrary to some advertising claims: OSHA nor API have specifications for
the design or metallurgic construction of a safety anchor. However they both have
specs on testing of the anchor and the anchor must meet these load requirements.
