NSA National Fence Assembly Video
National Steeplechase Foundation (NSF) closely partners with National Steeplechase Association (NSA) to enhance our sport's safety for horses.
In 2016, NSF sponsored an important "how-to" video for race meets, at the request of NSA's Safety Advisory Committee.
The video explains how to assemble brush fences to meet NSA's requirements. NSA fences are consistent from meet to meet.
Fence standards are under continual review by officials and horsemen for potential improvements. The new fence safety standards are the result of previous a NSF sponsored project, which involved using super slow motion cameras to capture horses jumping some NSA fences during race meets. A team of safety advisors analyzed the video data and concluded that adding a white line to the base of the roll top improved horses' ability to see their takeoff spots for a good jump.
Fences now consist of a steel frame stuffed with plastic "brush". The frames are stabilized on the jump landing side with two feet of steel rods, which ensure the frames do not tip as horses brush through the fences. On the takeoff side, large foam and rubber rolls are covered in green canvass. The green canvass covers also have wide white stripes, marking the ground line and the start of the brush.
