I have 2 6x6 MetalTech scaffolding units with outrigger support wheels and safety rail if they are being stacked up. They're both on wheels. Each unit is $30/week or both for $60/week. The Safety rail and outriggers are included if needed. I have adjustable 7-12 foot walk plank that can be rented for $10/week if needed to reach across a span from scaffolding unit to scaffolding.
