I’ll see if I can load up a pic of how mine looks. Images are broken on the forum right now so I might not be able to
When I got my OTTB mare, just a few months OT as a late 3yo, she arrived in the dark on a cold November night. My barn wasn’t finished, so pasture was the only option (I know, I know). My one horse Rio was nice and quiet, VERY happy to have a friend again (the real JB had died just a month before), so he hung out on his side of the fence, while she RAN her side of the fence. At one point she ran INTO the fence, and bounced off it.
When Rio was on paddock rest for a ruptured peroneous tertius tendon, he rolled into the fence. Twice. He also cast himself several times as a 2yo, so clearly spatial awareness was not his forte LOL. He got a leg tangled in the fence, jumped up, and ran 6-7 broken insulators later, the tape hit the tensioner, and broke. He had a little swelling, a little weepy skin from the “burn”, but was otherwise fine.
He also rolled into another section, later, took out a post, the tape merely came out of the tensioner, and he went happily grazing up the fence line, unharmed.
My homebred was doing whatever, I wasn’t home when it happened, took out a post, had some minor cuts up in his groin area.
3 different horses, 4 incidents, pretty unscathed.
I’ve seen horses roll into a wood fence and get a leg between 2 boards and break the leg. I’ve seen impacts into boards where they just bounced off, or the board broke and impaled the horse.
I have no idea what the scenario would have been like in each of these incidents with board, I just know what DID happen with this solid tape that doesn’t break at the drop of a hat, but does like to break before the horse does.
