Abstract
A ladder step attachment made of a single, unitary piece of extruded aluminum having no moving parts. The attachment has a horizontal standing surface improved with a gripping surface, the standing surface having two notches for engaging the rails of a ladder and extending partially between the ladder rails. A lip connected to the standing surface presents a resilient member to abut the back side of the rung. A substantially tube-shaped support has a tube wall. One part of the tube wall shares a portion of the standing surface and another part of the tube wall engages the ladder's rails. A bend at the top of the rail engaging tube wall separates that portion of the tube wall from a substantially vertical portion of tube wall above the bend to facilitate removal.
