How high should cross tie rings be installed?
Thanks a bunch! Paddy
That is going to depend on the width of your aisle and the height of your horses. My barn aisle where my cross ties are located is 10 1/2 feet wide and I have 15 hand horses.
The 5″ diameter tie rings are mounted approximately 80 inches from the barn floor. They are attached to heavily reinforced wall studs with 3″ x 3/8″ lag bolts. The cross tie ropes are each approximately 5 feet long when tied. I tie them to the cross tie rings with a quick release knot. Tying instead of hard splicing onto the rings allows you to find that perfect adjustment.
This set up works great for me and is featured in all of my books that show me grooming, vacuuming, clipping and tacking up my horses in that area.

Dear Cherry,
Thanks for the information. That was very helpful! My posts are 12 feet apart, my horses are 15 hands (give or take a couple of fingers). I ended up mounting 2 1/2″ tie rings about 72″ off the floor (before reading your response). I appreciate your suggestion to use quick release knots on the rings.
P.S. I LOVE the tie rings in your books!
