Abstract: Platform assemblies may be built up using a substantial number of inverted U-shaped vertical supports with platform hold down members that hold the platforms in place, thus avoiding slippage or pilferage. The hold down members form a unitary structure with the supports and platform assemblies to hold the platforms securely in place. The unitary structure of the scaffolding assembly with hold down members acts as a deterrent against pilferage of the platforms because the unitary structure does not allow the planks to be removed unless the platform assembly is substantially disassembled. It also reduces the steps required to assemble a secure platform assembly with hold down members thus saving time while still preventing slippage and pilferage. The hold down members have holes at each end, and these holes have a diameter slightly greater than the outer diameter (OD) of the guide pipes at the junctions between vertically extending pipes.
