You can think if cribber just like a drug addict. Where there is a will there is a way! I've seen horses crib on metal pipe corrals, on the vertical edges of sheds, and on 1/4 inch anti cast wood strips until they literally have no front teeth. You need to find out how bad the horse cribs. Some won't crib with a simple loosly adjusted cribbing strap but I've seen horses still crib in a stripped, hot saused, 12x12 stall with a properly adjusted cribbing collar. I think it is really going to depend on what kind of horse you have.
