ABSTRACT:
A side rail system for interconnecting layered sections of elongated scaffold staging with the sections respectively spanning pairs of opposing upper and lower support arms of pump jacks which respectively ride on spaced apart pump jack poles. The side rail system includes upright posts which are spaced along the staging. A pair of rods are associated with each of the posts. The rods confrontingly project from the respective staging sections. The posts are pivotally coupled to the rods and are secured to the rods by quick adjust pins to prevent separation of the rods and posts. A mid-rail as well as a toe board can be interconnected between the rails. An end rail system can also be included. The scaffolding arrangement can be used exteriorly with a brace onto a wall. It can also be used interiorly between roof and floor with appropriate height adjustment arrangement provided.
