The device includes a first and second mounting brackets in a spaced horizontally aligned relationship on a vertical surface. A catwalk is pivotable between a stored position and a deployed position between the first and second mounting brackets. A lip extends upwardly from the first mounting bracket. A flange is movably coupled to the catwalk to abut the lip when the catwalk is in the stored position retaining the catwalk in the stored position. The flange is movable relative to the catwalk to disengage from the lip allowing the catwalk to be pivoted into the deployed position. A rail is pivotally coupled to the catwalk.
