ABSTRACT:
Standard platforms are integrated into a mason's scaffold to reduce manufacturing and assembly costs. The standard platforms having hooks on both ends. The hooks are supported on lower horizontal members of respective rectangular frames. Platform fasteners are secured to each lower horizontal member with the standard platform hooks therebetween, thereby retaining the standard platforms to the frames to form a working deck. Each platform fastener comprises a metal sheet to which is welded an L-shaped bar that engages a hole in the frame lower horizontal member. A pin slides within the metal sheet and cooperates with the bar to positively secure the platform fastener to the frame lower horizontal member. Similar standard platforms and platform fasteners are assembled to upper horizontal members of the frames to form a protective canopy. Hatches with selectively openable doors may be used for some sections of the canopy. The present invention further comprises fairleads for guiding the cables from which the mason's scaffold is suspended from a building or the like.
