Like "Hilltop", I'm a masonry contractor, and I have a ton of different scaffolding in my arsenal. For those looking for 5x7 scaffold frames, or pretty much any scaffolding, I've found that this place is hard to beat. I've owned some of their stuff for nearly 20 years without issue, and I use it quite regularily.
