2 step fit perfectly. Tough to use threaded bolts provided for installation so husband got concrete anchor bolts instead. Much easier. We had gotten an estimate for a contractor to build wooden rails. These were a 3rd of the price.
The provided wall screws don't fit the hole in the brackets. The screws are to small and just fall through the bracket holes. I found some at Home Depot. Would have been easy installation otherwise. GOOD PRODUCT
