We designed Step Bracket to convert climbing ladder rungs into a steps. Step Brackets come 10 to a set (left and right).  We recommend 12-inches between steps, but if you are dealing with a bad knee, hip, or young children you can space the steps to the distance that best fits your needs. The Step Bracket easily attaches with #9 deck screws. We recommend using a 2″x 8″ treated wood for the actual step.
