We have the corral-lite corrals and I found not to use the
pins which connect the panels to each other. I use 5’ fiberglass poles in
place of the pins and hammer the poles into the ground. This also makes it
easier to swing the panels if needed (us, not the horses), thus easier to
change the shape of the corral, and the horses have a more difficult time in
raising the panels, especially if the proper amount of tension is used.
