Golden State Corral's. offers wash racks and hitching posts which can be incorporated into any grooming bay or wash facility. 

Both the wash rack and hitching post are fabricated from 2-3/8" (O.D.), CQ20, galvanized steel  for superior strength. This "heavy-walled" pipe ensures the security and safety of you and your horse.    

The wash rack incorporates a simple yet effective safety feature, employing a removable  rail at the rear for easy access into and out of the wash rack. Both the wash rack and hitching post are available with or without weld-on flange plates for masonry applications.

You'll appreciate the difference!
