Scaffolding. Very high quality old school built. Very light aluminum yet incredibly sturdy design. This scaffolding has served me so well at my home and farm for 10 years. Have run out of projects and I am getting older and probably shouldn't be up high so much. Just finished using it to re-roof part of our house and took these photos. I should hang onto it. You never know how it comes in handy. It is really nice for using indoors painting too. Just use a low set up and roll around a room painting ceilings and trim or fixing something. Very easy to set up and take down.
