I had tried another which only accommodated a 9" drop between 3 steps. This one however accomodate a "normal" 3 step rise of 7-8". It went together well, and installed quite easily, is sturdy too. I had a tight fit and the rail length went in the tight place on steps into the garage. Very happy and feel safe using it. Recommend it for 3 step situation, especially when a longer rail doesn't work. Suggest supplying both lag and cement bolts or give a choice. Had to purchase lag bolts as I installed on wooden steps.DV in Bend Oregon
