Refresh Your Knowledge on Frangible Technology

Did you know that the United States has more frangible fences than any other country? Frangible technology has been around for nearly 100 years with the British Pin taking the honors as the first formal frangible device. The study of frangible fences has continued in the last decade, including the USEA Collapsible Fence Technology Study which was conducted through the University of Kentucky from 2016-2018.

The USEA Foundation is proud to have had a strong focus on the continuing research and promotion of these critical safety devices all across the U.S. In 2020, an initiative was created in partnership with the USEA Foundation Frangible Technology Fund that would assist with the construction of frangible fences on cross-country courses at the Preliminary level and above around the country. New regulations as of December 1, 2023, now require courses at the Training level and above to utilize frangible technology as seen in the excerpt from the Eventing Rulebook below:


a. Whenever possible, Obstacles for which frangible technology (e.g., frangible pins, MIM Clips, or any other load relieving device) is appropriate must be constructed or retrofitted with frangible technology for the Training level and above.

b. The Technical Delegate must confirm with the Ground Jury and Course Designer that the frangible technology employed is consistent with the applicable manual for the approved frangible technology. At a minimum, frangible technology devices used at national and FEI Events must meet the FEI Updated Standard for Frangible/Deformable Cross Country Fences. Training fences constructed prior to May 1, 2023 may remain as such through December 31, 2023 but must be upgraded or retrofitted to meet this rules as of January 1, 2024. All fences constructed after May 1, 2023 must meet this rule.

In an effort to help mitigate the cost of this endeavor for events, organizers may apply for funding through the Foundation’s Frangible Technology Fund here. Venues hosting events at the Advanced level and below will be awarded $2,000. Venues hosting events at the Intermediate, Preliminary, or Modified level and below will be awarded $1,500. Venues hosting events at the Training level and below will be awarded $1,000. All grants are to be used for the purchase of any materials (lumber, frangible technology equipment, etc.) to assist with the construction of frangible fences on their cross-country courses. The Foundation highly encourages each event to apply for this funding!

Further endorsing the importance of utilizing this equipment, the FEI conducted a review of falls per fence type from data collected from 2016-2023 and the results show a decrease in horse falls when frangible technology is utilized. For example, during that seven year period, a total of 1914 horse falls were recorded across the globe. Of those falls, 1,703 were at fences that did not equip frangible technology and only 211 were at fences which did utilize frangible technology. Of the 51 serious horse falls during this time period, only one was at a fence with the new standard of frangible technology, four were at a fence with the old standard of frangible technology, and 46 were at fences with no frangible technology. You can access the full FEI report here.
