A step is attachable to a mounting wall without the use of tools. The step has latching T-tabs at outer ends of legs formed into a V shape. The latching T-tab of a lower leg can be twist locked into a formed slot by inserting the lower leg through the lock slot in one position and rotating it to a working position. The second leg forms a step surface and is latched to the supporting wall after the first leg is rotated to locking position. |
