This is a very popular set in the masonry industry and allows someone up to 6' tall to walk easily underneath unobstructed. However, this set does not allow the same freedom of board placement as other sets. This can be a great base for any sidewalk scaffolding/shed set-up. Our 5' X 6'6" premium walk-through set meets and/or exceeds all OSHA regulations.The frames use our c-locks for added safety and security. To maximize the life and longevity of our scaffold sets we apply a high visibility yellow powder-coating.
